HELMUT A. ABT, Emeritus Astronomer
Research Interests
Formation and evolution of double stars; publication statistics
FY06 Accomplishments:
Abt considered the eccentricities of 553 spectroscopic and 616 visual binaries with known orbital
elements and dwarf primaries. These show that for long periods (P>275 yrs), all eccentricities are equally
probable, indicating that when wide binaries are formed, no single eccentricity is preferred. For shorter
periods due to tidal interactions, the highest eccentricities disappear first until, for the shortest periods,
only the zeros remain. Abt also considered the papers published in the major journals in five sciences
(physics, astronomy, geophysics, mathematics, and chemistry). The numbers of papers published
annually since 1970 divided by the numbers of members of the appropriate scientific society (e.g.
American Physical Society) are constants, indicating that the numbers of scientific papers depend only
on the numbers of research scientists and not upon the quality, sensitivity, or quantity of the instruments
and computers that they used.
Abt presented talks in China on “Early Chinese Inventions” and “National Astronomical
Productivities” at Nanjing University and the Purple Mountain Observatory in Nanjing; “Stellar Disks
and the Interstellar Medium” at National Astronomical Observatory, Beijing; “Early Chinese Inventions”
at Beijing Normal Univ. Beijing. Abt attended the Seventh Pacific Rim Conference on Stellar
Astrophysics in Seoul, South Korea, in November 2005, and gave talks on “The First Six Pacific Rim
Conferences” and “Tidal Effects in Binaries.” He attended the Centennial Celebration for Dorrit Hoffleit
at Yale Univ. in April 2006, and gave a talk on “Spectral Classification Surveys.” Abt attended the IAU
General Assembly in Prague, Czech Republic, and IAU Symposium No. 240 on “Binary Stars as Critical
Tools and Tests in Contemporary Astrophysics,” and gave a talk on “Observed Orbital Eccentricities.”
Abt wrote eight papers.
FY07 Plans
Abt will attend, by invitation, a conference on “Astronomical Communication” in Brussels,
Belgium, June 10-13, 2007, and give a paper. He has a tentative invitation to give several talks in China.
Abt will do research on binaries among high-velocity stars, on metallic-line (Am) Stars, and on
publication statistics.

Research Interests
Stellar atmospheres; stellar winds; fundamental properties of stars; interferometry; spectroscopy;
radiative transfer; modeling
FY06 Accomplishments
Aufdenberg and colleagues (including S. Ridgway) published their interferometric observations and
modeling of the important photometric standard Vega. This work supports the model of Vega as a poleon rapid rotator. In addition, Aufdenberg was a co-author on three published interferometric studies
based on data from the CHARA Array on Mount Wilson: the detection of Vega’s debris disk in the Kband, measurements of M-dwarf angular diameters, and the detection of circumstellar material
surrounding delta Cephei and Polaris. Aufdenberg was also a co-author of a study on the limb darkening

NOAO ANNUAL REPORT FY 2006
of the star SV Cam based on a comparison of model atmospheres to precise multi-band photometry from
the Hubble Space Telescope. Aufdenberg also contributed models for a published multi-wavelength
study of the prototypical symbiotic star Z And. This work puts forth a new, two-stage model for the
symbiotic outburst. Aufdenberg collected additional interferometric data on hot stars Rigel and Spica and
presented the first results on Spica as an invited talk in a symposium at the International Astronomical
Union General Assembly in Prague. Aufdenberg left the NOAO staff in early August 2006. He is now an
assistant professor in the Physical Sciences Department at Embry-Riddle Aeronautical University in
Daytona Beach, FL.
DMITRY BIZYAEV, Research AssociateS
Research Interests
High-resolution stellar spectroscopy; stellar radial velocities and chemical abundance; star formation in
collisional ring galaxies; structure of spiral galaxies; dark halos
Bizyaev and V.V. Smith continued selection of radial velocity stable red giants for the SIM Planet Quest
mission (under NASA grant through JPL). During 121 nights (96 observing ones) at the 82–inch
telescope (McDonald Observatory, Texas), 2490 spectra were obtained and all spectra were reduced.
Parameters and history of star formation in collisional ring galaxy Arp 10 were studied via the modeling
of emission and absorption spectral features (in collaboration with the UWO, Canada; SAO RAS,
Russia). Development of the bending instability in galactic disks was studied (in collaboration with
Volgograd Univ., Russia). Structural parameters of 140 edge-on galaxies, including extinction-free disk
thickness, were estimated from 2MASS NIR images.
FY07 Plans
Bizyaev will continue the observations of SIM reference stars. He and V.V. Smith expect to estimate
radial velocity variation and abundances [Fe/H] for most objects from their sample (about 1400 stars).
Studies of propagating star formation in collisional ring galaxies will be continued. Connection between
dark halos and stellar disks properties will be studied with the help of edge-on spiral galaxies.
ROBERT BLUM, Associate Astronomer, NOAO/NGSC
Research Interests
The Galactic Center; massive star formation; resolved stellar populations
Blum, in collaboration with PI Meixner (STScI) and colleagues, continued as lead of the evolved stars
group (one of three science groups) on the Spitzer Space Telescope SAGE survey. This second
generation Legacy program surveyed the LMC in all IRAC and MIPS bands. Two papers were accepted
in refereed journals of which Blum was lead author on one. Blum is funding postdoc. Sean Points at
CTIO through a sizable Spitzer grant related to the SAGE project (with Co-I Olsen of CTIO). Blum
continued his collaboration with Conti (JILA) and Damineli (U. Sao Paulo) to investigate Galactic Giant
HII regions with a five-night run on the CTIO 4-m. Blum participated in first science use of the new
integral field spectrometer, NIFS, at Gemini North as a member of PI McGregor’s (ANU) NIFS science
team.
FY07 Plans
Blum will continue exploiting the SAGE data set. His evolved star group should produce several more
papers this year including a first author for postdoc. Points on the properties of LMC clusters as seen

through SAGE. Blum will continue the program to investigate Galactic Giant HII region stellar content.
His group’s ninth paper in this effort is nearly ready to be submitted (lead author Lys Figueredo, a former
student of Damineli and now at Open University in the UK). This program seeks to understand massive
star formation and Galactic structure and uses the NOAO 4-meters and both Gemini 8-meter telescopes.
Blum is reducing a NIFS data set on two Galactic Giant HII regions taken during the 2006 PI time of
McGregor at Gemini North. This data set will result in a first author paper for Blum this year.
TODD BOROSON Astronomer (Deputy Director, NOAO)
Research Interests
Structural and physical properties of active galactic nuclei; stellar populations and their evolution; O/IR
instrumentation; analysis and mining of large astronomical data sets
Boroson continued to work on reduction of the Gemini IR spectra of QSOs obtained in the previous year.
For the automatic measurement of QSO spectral properties, he has developed tools that utilize K-L
transforms to produce relatively noise-free versions of the many thousands of SDSS QSO spectra. A
number of new correlations among spectral properties are seen in the resulting database. In addition, in
collaboration with D. Schneider and M. Eracleous (Penn State U.), he has begun a study of possible
binary black hole AGN, in which the H-beta line peak is offset from the systemic velocity by thousands
of km/s.
FY07 Plans
Boroson plans a 6-month sabbatical in FY07, during which he will use the automatic tools developed in
the past year to complete the analysis of the low-redshift SDSS QSO spectra and interpret the observed
characteristics in terms of physical parameters. Spectra of the sample of possible binary black hole AGN
will be analyzed in search of evidence that the offset H-beta peaks are shifting.
KATHERINE J. BRAND, Research Associate±
SEAN D. BRITTAIN, Research Associate (Michelson Fellow, NASA)±
CHRISTINE CHEN, Research Associate (Spitzer Fellow, NASA)S
Research Interests
Star and planet formation
Chen, in collaboration with the IRS Disks team (led by D. Watson, University of Rochester), modeled
Spitzer IRS 5–35-micron spectra of ~60 nearby IRAS-discovered debris disks. She assumed that
circumstellar dust was either located in (1) a ring around the star, or (2) a continuous disk that is
produced as particles spiral into the central star under the Poynting-Robertson effect. Chen found that the
spectra are better fit by a single temperature black body, suggesting that the inner regions of the disks
have been cleared and that the disks are collisionally dominated. In collaboration with A. Li and the Fab4
team (led by K. Stapelfeldt, JPL), Chen modeled the Spitzer IRS 5–35-micron spectrum of beta Pictoris.
She reported: (1) the first detection of weak crystalline silicate emission features at wavelengths lambda
> 20 microns, (2) upper limits on the atomic and molecular gas masses, and (3) that photon-stimulated
desorption may produce the observed atomic Na I gas seen in Keplerian rotation.
A-3
FY07 Plans
Chen hopes to continue to study the dust and gas around young stars in Sco-Cen. In collaboration with
M. Jura (UCLA), she hopes to complete a Spitzer MIPS search for 24- and 70-micron excesses around
100 solar-like stars in ScoCen, and, in collaboration with the IRS Disks team, to use Spitzer IRS and
MIPS SED mode observations to follow up discoveries of debris disks. She will use follow-up
spectroscopy and SED-mode observations to determine the minerology and the structure of circumstellar
disks. In collaboration with J. Najita and M. Meyer (Steward), Chen hopes to obtain high-resolution
visual spectra of her ScoCen targets to search for accretion signatures and circumstellar atomic
absorption features. In collaboration with M. Jura and M. Munno (Caltech), she hopes to obtain x-ray
observations of her ScoCen targets to determine whether stellar wind drag is an effective dust grain
removal mechanism around solar-like stars with ages ~10 Myrs.
CHARLES F. CLAVER, Scientist
Research Interests
Age and history of the Milky Way; stellar populations; large optical/infrared telescopes; Large Synoptic
Survey Telescope; astronomical instrumentation; atmospheric physics
As telescope/site scientist for the Large Synoptic Survey Telescope (LSST), Claver has continued his
work on the design and development of the 8.4-m 3.5-degree field-of-view telescope system. In
particular, Claver, Phillion (LLNL), and Upton (NIO) have worked to develop an optical compensation
strategy and show that the LSST optical design can be realized within reasonable tolerances. In addition,
Claver, working with Corson (WIYN) and an outside consultant, has developed new wavefront curvature
analysis software to work with the unusual pupil geometry. Claver, Burke (SLAC), Rosenberg (LLNL),
and scientists from the LSST collaboration have completed a coordinated campaign using SOAR and
Gemini South to evaluate the effects of atmospheric turbulence on estimating weak lensing induced
shear. The results of this work have resulted in one submitted journal paper, Asztalos et al, “Properties of
Ellipticity Correlation with Atmospheric Turbulence from Gemini” submitted to the Astrophysical
Journal and one paper in preparation describing the wavefront correlations at SOAR. Claver and Mighell
(NOAO) worked with REU student M. Stone over the summer to analyze data from two successful
observing runs with the WIYN Tip-Tilt module to observe the distant compact open clusters NGC-1193
and Be54. The high angular resolution from WIYN and the tip-tilt module enabled more precise and
deeper photometry than had been done previously.
FY07 Plans
Claver plans to continue his work on the LSST project toward detailing the telescope design and control
in preparation of a Conceptual Design Review. Claver, with others from the LSST project, will install an
infrared all-sky camera on Cerro Pachón to evaluate the relationship between IR imagery and visible
extinctions as part of LSST calibration studies. He will also continue leading the development of the
alignment and wavefront sensing strategy for the LSST active optics control system. Claver will also
continue in his role as interim LSST Systems Engineer until a full-time replacement can be found. He
plans to continue his observation work on old open clusters in the Milky Way.
STEVEN K. CROFT, Senior Science Education Specialist (Astronomer)
Research Interests
Variable stars; planetary geology and geophysics
A-4
Croft continued his work in formal and informal science education. He continued work on the
Investigating Astronomy project in partnership with TERC, providing scientific content and images to
the effort that will produce the first new astronomy textbook in 20 years aimed at high school students.
He also continued to develop an asteroid research project aimed at middle school students in support of
the Large Synoptic Survey Telescope educational outreach effort. He continued in the TLRBSE
program, providing technical support and running the project’s remote-controlled telescope program.
Croft wrote and submitted a new educational proposal tied to NOAO’s International Polar Year science
proposal, “Astronomical Site Survey of the Antarctic Plateau.” He also began work on the educational
outreach project supporting the Giant Segmented Mirror Telescope project.
FY07 Plans
Croft will continue work on the Investigating Astronomy project, participating in content development
and scientific reviews, and providing the numerous images and other astronomical data sets needed for
the project as it moves into its third year. He will also continue developing the asteroid research project
for the LSST EPO program, the GSMT EPO project, and, if funded, the Antarctic Site Selection project.
He will also continue coordinating the remote telescope portion of the Teacher Observing Program and
provide technical support to the TLRBSE program.
EMMANUELE DADDI, Research Associate (Spitzer Fellow, NASA)±
ARJUN DEY, Associate Astronomer
Research Interests
Galaxy evolution; high-redshift galaxies; large-scale structure; AGN evolution and clustering
Dey is one of the two PIs (with Jannuzi) of the NOAO Deep Wide-Field Survey (NDWFS), an
investigation of galaxy evolution and clustering over an unprecedented volume. This survey has spurred
a huge investment in ground- and space-based resources (VLA, Westerbork, Spitzer, MMT, Keck,
GALEX, Chandra), and the resulting unique multi-wavelength database is allowing a comprehensive
study of galaxy evolution and structure formation in the 0<z<5 range. The optical data from the Bootes
field of the NDWFS, publicly released, is now the focus of much of Dey’s research. During the last year,
Dey was involved in the spectroscopic follow-up of galaxies and AGN selected from the NDWFS, in
particular focusing on mid-infrared sources in the field. This resulted in the discovery of a significant
sample of extremely red galaxies at z~2 that appear to be undergoing an active phase of star and AGN
formation. Dey is now investigating these objects using HST, Keck and the CSO. With postdocs K.
Brand, M. Brown and other collaborators, Dey continues to investigate the evolution of the X-ray
luminosity, mass, color, number density, and clustering of normal, early-type galaxies between 0<z<1.
Dey was the Study Scientist for the Feasibility Study for the Gemini Wide-Field Multi-object
Spectrometer (WFMOS), a next-generation instrument providing a highly multiplexed (~4800 fiber),
wide-field (1.5 deg) spectroscopic capability for the Gemini community. The Gemini Observatory is now
attempting to partner with the Subaru Observatory to realize this capability. The Study, completed in
FY05, was well received, and is now proceeding to a Conceptual Design Study Phase.
FY07 Plans
During the upcoming fiscal year, Dey will be on sabbatical. During this period, he will continue to work
primarily on galaxy evolution and clustering, using the NDWFS and related survey data. He plans to
continue studying the clustering and evolution of the red envelope galaxy population, investigating the
growth of the central black holes in these systems, and studying the high-z Lyman break galaxy
A-5
population. Along with M. Prescott (Univ. of Arizona graduate student), Dey is beginning a study of the
space density of large Lyman Alpha-emitting nebulae and the constraints they place on the formation of
massive galaxies. He is also helping to organize a Tucson workshop on the formation of massive
galaxies. Dey will participate in the WFMOS Conceptual Study (being led by the AAO) in the role of
Survey Scientist, organizing the core science teams to carry out the two key scientific projects (a Dark
Energy study and a Galactic Archaeology study). Dey is also leading a study of the impact of a possible
field-of-view descope of the WFMOS key science projects.
DAVID DE YOUNG, Astronomer
Research Interests
Theoretical astrophysics, especially non-linear phenomena; galaxy clusters; active galactic nuclei;
extragalactic radio sources; MHD processes
De Young completed and published (ApJ 1 Sept 2006) a series of calculations that examine the content
of extragalactic radio jets. Until now, the only known components in these objects were relativistic
electrons and magnetic fields. However, the combination of recent x-ray and radio observations of radio
sources in rich clusters allowed for the first time accurate calorimetry of radio sources. Knowledge of the
total energy present in these objects then permits limits to be placed on the nature of the particle content
in the jets that supply the extended sources. De Young, in collaboration with T.W. Jones (U. Minnesota)
and S.M. O’Neill (U. Minnesota), also completed an extension to three dimensions of time-dependent
numerical MHD simulations of the evolution of radio sources in clusters of galaxies. These calculations
will extend the previous set of two-dimensional studies completed in FY05, and they should provide a
definitive view of the evolution of these objects and their contribution to reheating of the intracluster
medium.
FY07 Plans
De Young will continue work on the evolution of radio sources in clusters, using the recently completed
3-D extension of the MHD calculations mentioned above. Detailed calculations of the evolution of
“heavy” jets from AGN are being initiated, as are new calculations of mass entrainment in collimated
outflows that include self-consistent evolution of magnetic fields. De Young will also continue
collaboration with T. Rector (U. Alaska) on the evolution of compact outflows in the nuclei of galaxies.
MARK DICKINSON, Associate Astronomer
Research Interests
Galaxy formation and evolution; galaxy clusters and large-scale structure; quasar absorption line
systems; evolution of active galaxies
Dickinson successfully proposed for a second Spitzer Legacy science program, described in more detail
below in FY07 Plans. The Legacy projects are major surveys using large amounts of Spitzer observing
time to produce public data products useful for addressing a variety of important scientific problems. At
NOAO, Dickinson coordinated most of the logistics for the GOODS data reduction and delivery, and for
ground-based supporting observations. He continued an NOAO/TSIP program of Keck spectroscopy
targeting 24-micron sources at 0.8 < z < 2.5 and Lyman break galaxies at 3.5 < z < 6.5. Along with other
members of the GOODS science team, Dickinson has been analyzing the stellar populations and masses
of high redshift galaxies selected in a variety of ways, as well as the dust-obscured energetics of star
formation and active galactic nuclei. The survey has identified and spectroscopically confirmed galaxies
A-6
at z~5 to 6 with stellar masses approaching that of today’s Milky Way, as well as highly tantalizing (but
as yet unconfirmed) candidates for much more massive galaxies at still higher redshifts. GOODS 24micron data has also uncovered a very numerous population of luminous and ultraluminous infrared
starburst galaxies at 1.5 < z < 3. Dickinson worked with NOAO postdoctoral fellows Daddi and
MacDonald on science from GOODS, including efforts to calibrate the derived star formation rates using
multiwavelength data. Their work showed that this redshift interval was the epoch in which today’s most
massive galaxies appear to have formed most of their stars. Dickinson has been working with
collaborators at the SSC and other institutions to obtain IRS follow-up spectroscopy of faint 24-micron
sources in GOODS, and 16-micron imaging over both GOODS fields.
FY07 Plans
Dickinson, along with NOAO postdoc researchers N. Reddy and S. Salim, will work on science from the
new Legacy program and from GOODS. The Legacy program will obtain deep Spitzer/MIPS
observations over three fields with a combined solid angle roughly 7x that of GOODS. In particular, the
project will be geared toward very deep 70-micron observations. Previously, most Spitzer surveys at
wavelengths longer than 24 microns were too shallow to detect any but the most hyperluminous and
exotic objects at z > 1. The new program will expose 12 times longer than in the MIPS GTO deep
surveys, enough to detect a significant number of luminous infrared galaxies at 1 < z < 2. These data will
sample dust emission in the 25–35-micron rest frame wavelength range, which Spitzer surveys of nearby
galaxies have shown correlates extremely well with star formation, avoiding many of the physical and
observational complexities of the shorter mid-infrared wavelengths where PAH emission and silicate
absorption dominate the spectrum. The 70-micron data will thus help interpret and calibrate the more
sensitive but also more ambiguous 24-micron data. In combination with radio and submm observations
of these fields, Dickinson, Reddy and Salim will also measure dust temperatures in galaxies at high
redshift. The new program will also obtain 24-micron imaging at “near-GOODS” depth over a much
larger area than GOODS. The combined 24- and 70-micron data offer a powerful means to identify
heavily obscured AGN by their warm dust emission. Observations for the new program began in early
September 2006, and will continue through the summer of 2007.
JONATHAN H. ELIAS, Astronomer
Research Interests
Star formation and evolution; Magellanic Clouds; supernovae
Elias was the NOAO lead on a feasibility study for the Thirty Meter Telescope mid-infrared echelle
spectrograph (MIRES) and provided support for other TMT instrument development activities. The
MIRES feasibility study was completed and reviewed in March. Elias was designated the NOAO Project
Scientist for TMT in February.
FY07 Plans
Elias’ scientific activities planned for FY07 will be almost exclusively in support of TMT, including, but
not limited to, support of the TMT SAC and systems engineering effort.
KATY GARMANY, Associate Scientist (Senior Science Education Specialist)
Research Interests
Formation and evolution of massive stars
A-7
Garmany took over management of the TLRBSE program, including recruiting teachers, teaching an online component and organizing the summer workshop, including 4 nights at Kitt Peak. She managed the
teacher/student observing program (TOP) and handled groups at the 0.9-m, and is developing a student
project using data from this telescope. She taught Astronomy 101 at the Tohono O’Odham Community
College in Sells, and worked with the College as they prepared an NSF proposal for increased science
and math at TOCC. She collaborated on two successful science education proposals with other NOAO
scientists.
FY07 Goals
Garmany will manage the transition of the TLRBSE program to in-house funding and refine the focus of
this program. She will continue to work with the Tohono O’Odham to increase communication, both
through the community college and through other contact in the community. Garmany expects to
complete work on a major revision of the TLRBSE (now Astronomy RBSE) Web site and incorporate
material developed as part of her other EPO grants.
KENNETH H. HINKLE, Scientist
Research Interests
Peculiar and late-type stars; circumstellar and interstellar matter; molecular spectroscopy;
instrumentation
Hinkle, with Wallace (NOAO), Ayres (CASA), and Valenti (STScI), published a monograph on
observations of and line identification in the Arcturus UV spectrum. Hinkle continued his work on the
evolution of late-type binary systems. Papers were published in collaboration with Fekel (Tennessee
State), Joyce (NOAO), Lebzelter (Vienna), and Wood (ANU) on the evolution of the neutron star-AGB
binary V2116 Oph and several white dwarf-red giant systems. Hinkle continued work with Lebzelter on
Spitzer observations of circumstellar shells around 47 Tuc AGB stars. Hinkle also collaborated with
Brittain (Clemson) and Lambert (Texas) on circumstellar disks. Hinkle authored one paper and coauthored an additional three SPIE papers resulting from the design of the high-resolution near-infrared
spectrograph HRNIRS.
FY07 Plans
Hinkle will continue work on high-resolution, near-infrared spectrographs. In addition to work on
instrumentation, Hinkle will continue several ongoing collaborations with Lambert, V. Smith, and Cuhna
(NOAO) on abundances of evolved stars. Additional observations of orbital data for evolved late-type
binaries with publications in collaboration with Fekel and Joyce are envisaged. Hinkle will also continue
working on several projects concerning infrared observations of circumstellar and circumbinary shells
and disks in collaboration with Brittain and Lebzelter.
BUELL T. JANNUZI, Associate Astronomer (Acting Director and Deputy Director, Kitt Peak National
Observatory)
Research Interests
Observational cosmology; formation and evolution of large-scale structure; quasars and quasar
absorption line systems; instrumentation for surveys
A-8
Jannuzi continued work as Co-PI with A. Dey on the NOAO Deep Wide-Field Survey (NDWFS), an 18
square degree optical and near-IR imaging survey designed to study the formation and evolution of
galaxies and large-scale structure in the Universe. The survey covers two sub-fields located in the
constellations Boötes and Cetus. The primary observations for the NDWFS were completed in 2004, but
processing of the images continued in FY06. The Boötes field images and catalogs were released in
October 2004. Jannuzi has been preparing the Cetus data for release during FY07. Over 100 papers have
already made use of these data to study a variety of astrophysical problems, and additional papers are in
preparation. In FY06, Jannuzi co-authored 14 of these papers covering a diverse set of topics, ranging
from “The Evolving Luminosity Function of Red Galaxies” (Brown et al., 2006) to a study of rare
objects found by their mid-IR properties (Stern et al., 2006).
Jannuzi co-authored additional papers in FY06 studying clusters of galaxies and the properties of
AGN. His ongoing studies of the intergalactic medium resulted in the paper, “The Association between
Gas and Galaxies II: The 2-point Correlation Function,” submitted, with R. Willman, S. Morris, A.
Shone (Durham U.) and R. Dave (U. of Arizona), to MNRAS during the summer of 2006.
FY07 Plans
Jannuzi plans to complete a study (in collaboration with J. Bechtold) of the physical properties of
Lyman-alpha absorption line systems using HST/STIS UV spectroscopy of intermediate redshift quasars.
He will also remain involved in analysis of several recently completed surveys: the Large Area Lymanalpha (LALA) Survey (PIs Rhoads and Malhotra), AGES (AGN Galaxy Evolution Survey; PIs
Kochaneck and Eisenstein), and CHAMP (The Chandra Multi-wavelength Project; PI P. Green). Jannuzi
will continue as a co-I in the IRAC Shallow Survey (PI Eisenhardt), the deep near-IR imaging survey
(FLAMEX, PIs Elston and Gonzalez), and the Spitzer MIPS (PI Soifer) imaging surveys that are observing
portions of the NDWFS survey fields. Jannuzi is co-I on several HST and Spitzer programs approved for
time during 2006. With these programs he will study the evolving properties of galaxies as a function of
time.
RICHARD R. JOYCE, Scientist
Research Interests
Late-type stars; mass loss; infrared detector and instrumentation development
Joyce continued a long-term project with Hinkle (NOAO) and Fekel (TSU) to determine orbits of
symbiotic stars by measurement of their radial velocities at infrared wavelengths, emphasizing the
largely unstudied Southern sky. The results for V2116 Oph, a rare neutron star symbiotic, were published
and results for several other symbiotics were accepted for publication. The same observational
techniques were used to measure the pulsation of long-period variable stars in 47 Tucanae. Joyce also
collaborated in a study of carbon and oxygen abundances in metal-poor globular cluster stars, using highresolution infrared spectra obtained with Phoenix on Gemini South.
FY07 Plans
Joyce will continue the infrared radial velocity measurements of the Southern symbiotic stars and the
abundance studies of globular cluster stars. He will use awarded observing time with IRMOS on the
Mayall telescope to survey a number of Planetary Nebulae at high spectral resolution in the infrared. One
goal is to identify lines of uncommon elements whose presence may be diagnostic of neutron-capture
processes in the progenitor star.
A-9
TOM KINMAN, Emeritus Astronomer
RESEARCH INTEREST
Galactic structure; galactic halo; horizontal branch stars; RR Lyrae stars
FY06 ACCOMPLISHMENTS
Kinman acquired and partly reduced 706 frames of 77 RR Lyrae stars mostly in Lick Survey fields using
the 32-inch Tenagra telescope. Kinman, with Clewley (Oxford), worked on improving SDSS ugr to UBV
transformations and published a paper with him showing possible spatial clumping in BHB stars found in
an SDSS survey. Kinman, with Cacciari (Bologna) revised distances of 117 NGP halo stars and found
that the RR Lyrae stars, but not BHB stars, showed strong retrograde motion (agreeing with Borkova and
Marsakov). Kinman collaborated with Morrison (Case) to get improved samples for an analysis of the
local halo, and contributed both visual and IR photometry (and some spectroscopy) of local halo stars
collected over the years.
FY07 PLANS
Kinman will continue CCD photometry of RR Lyrae stars in Lick fields if the Tenagra telescope is
available, and will reduce existing data from this telescope. Kinman will publish his nearly completed
discussion of halo kinematics at the NGP and follow this with a paper giving the data on which this is
based. This will include a comparison of the Johnson colors with those from 2MASS, SDSS, etc. An
updatable version will be put on the Web. Kinman will continue work with Clewley on photometric
transformations and halo clumps. Kinman will continue the collaboration with Morrison, Helmi et al.,
which aims to find local halo “groups” using angular momenta diagrams.
TOD R. LAUER, Associate Astronomer
Research Interests
Extragalactic astronomy; normal galaxies; nuclear black holes; stellar populations; cosmology;
astronomical image processing; space-based astronomy platforms
Lauer was Principal Investigator of a successful NASA profile to define the Destiny concept for the Joint
Dark Energy Mission. Desinty is a Near-IR Space Telescope that will use supernovae and weak lensing
as dark energy probes. Lauer was the lead author on two major papers on the central structure of
ellipticals galaxies, one ratifying the bimodal central structure of galaxies, and the second concluding that
extremely high mass black holes may reside at the center of the brightest cluster galaxies (BCG). To test
this hypothesis, Lauer and a number of his colleagues on the “Nuker” Team have begun a program of
using the Keck OSIRIS instrument with laser adaptive optics to weigh black holes at the centers of
BCGs.
FY07 Plans
Lauer’s major task will be to lead the Destiny JDEM study. Current plans are that NASA will review the
overall status of JDEM in 2007 to decide if a mission can be undertaken in the near future. Lauer will
also continue to work on measuring the properties of black holes in the most massive galaxies. Lauer also
will be working on the HST program on the structure of the M31 nucleus, the stellar population of M31,
and searching for microlensing events in M87.

TING-HUI LEE, Research Associate (NASA)S
Research Interests
Late stages of stellar evolution; Galactic and extra-Galactic planetary nebulae (PNe); mechanisms of
shaping PNe; radiative transfer; eclipsing binaries
Lee and collaborators completed the analysis of high-resolution spectra of eight Galactic planetary
nebulae. She and Stanghellini (NOAO) obtained HST/ACS prism observations of 11 PNe in the Small
Magellanic Cloud. The UV spectra provided essential carbon emission lines to determine carbon
abundances of these PNe and probe the cosmic recycling of the interstellar material in the SMC. In
collaboration with J. Lim (ASIAA) and S. Kwok (UHK), Lee also completed analyses of optically thick
radio cores of narrow-waist bipolar nebulae.
FY07 Plans
With Stanghellini, Lee will continue her work on the analysis of carbon abundances of SMC PNe. She
has started and will continue reducing ground-based spectroscopic data of LMC and SMC PNe to study
their nebular abundances. She will continue collaborating with Lim and Kwok to investigate the
structures and properties of radio cores of bipolar PNe using VLA. In addition, she will join the Kepler
mission and work with Howell to investigate planet transits and eclipsing binaries in the Kepler field.
JENNIFER LOTZ, Research Associate (Leo Goldberg Fellow)¬
Research Interests
Galaxy evolution; galaxy mergers; extra-galactic globular clusters; dwarf galaxies
Lotz continued her program to study the role of galaxy mergers in the evolution of galaxy morphology
and star-formation. With the Extended Groth Strip team, Lotz lead the efforts to analyze the HST ACS
survey of ~700 square arcmins in the Extended Groth Strip. Lotz submitted a major paper on the
evolution of galaxy morphology and merger rate in the Extended Groth Strip over the previous 8 Gyr.
Although the observed galaxy merger rate evolves weakly at redshift less than 1, it is sufficient to
produce a significant population of red spheroidal merger remnants. Other projects with the EGS team
included studies of the importance of mergers and interactions in triggering AGN activity (with C.
Pierce, UCSC), the kinematics of morphologically-disturbed galaxies (S. Kassin, UCSC), and the starformation rates per unit stellar mass of mergers and close pairs (L. Lin, NTU). Lotz also continued her
analysis of simulations of major gas-rich galaxy mergers with the UCSC theory group (J. Primack, P.
Jonsson, T. Cox). She was a Co-I on a successful HST archival proposal and a Spitzer theory proposal to
study the morphologies, spectral energy distributions, and dust properties of simulated minor mergers
and mergers with AGN feedback (PI Jonsson).
Lotz was the sole co-author on a major paper submitted by B. Miller (Gemini) on the globular
cluster systems of ~70 dwarf elliptical galaxies. They find that the dE globular cluster systems show less
evidence for cluster disruption than cluster systems in massive galaxies. They also find that the ratio of
globular clusters to host galaxy stellar mass increases strongly for less massive galaxies, indicating that
field star formation may be less efficient in less massive galaxies.
FY07 Plans
Lotz plans to continue her program to study galaxy mergers. Her top priority is to complete the analysis
of galaxy merger simulations, including the new simulations of minor mergers and mergers with AGN
feedback, as these are needed to calibrate the timescales for merger-driven morphological disturbances
A-11
and star-bursts. With the EGS and GOODS teams, she also plans to extend her study of mergers at
redshifts less than 1 and study the distribution of merger masses, star-formation rates, colors, and
kinematics to place tighter constraints on the evolution of merger remnants and galaxy assembly
processes.

Research Interests
Observational cosmology; physics; instrumentation
Lynds spent the full year focused primarily on a study of the potential of various locations on the
Antarctic plateau as possible sites where major investment in astronomical facilities would provide
observations of outstanding merit. This study has involved an investigation of the nearly unique
meteorological conditions on the plateau and their relationship with the large- and small-scale
topographic circumstances of sites. The work has depended heavily on an analysis of the extensive
radiosonde data available for the South Pole and on remote sensing data from satellite observations.
FY07 Plans
Lynds expects to continue studying the meteorology of the Antarctic continent as it relates to its
astronomical suitability for major observatory development.

stars; large-scale structure (redshift surveys, peculiar velocity surveys)
Macri authored a paper on a new absolute calibration of the Cepheid Distance Scale through the
discovery of Cepheid variables in the “maser galaxy” NGC 4258 using HST/ACS. He presented results
from this project at several conferences, including the Latin American Regional IAU meeting in Pucón,
Chile. Macri was co-author of two publications that made use of his ongoing work on the 2MASS
Redshift Survey. The survey started its next phase with the award of 300 hours of time at the GBT and
Parkes radio telescopes to undertake a peculiar velocity survey based on the Tully-Fisher relation. Macri
was a Co-I in two large HST proposals that were awarded 376 orbits in Cycle 15 to study Cepheids in the
Coma Cluster and in the hosts of type Ia SNe.
FY07 Plans
Macri will author several publications based on follow-up observations of Cepheids in NGC 4258 using
NICMOS, ACS/HRC and GMOS-N. He will also work on the planning and early data reduction and
analysis of the two large Cycle 15 proposals mentioned above. He hopes to be among the first users of
NEWFIRM at the Kitt Peak 4-m telescope in order to accurately calibrate his extensive Gemini nearinfrared imaging survey of M33.

image-analysis applications; astrophysical applications of low-count statistics
In a collaborative research effort with the Spitzer Space Telescope’s Infrared Array Camera (IRAC)
instrument team, Mighell has analyzed IRAC Channel 1 data of a single bright isolated star and has
demonstrated a new analysis method which yields an improvement in photometric precision of more than
100% over the best results obtained with aperture photometry. Mighell, Claver, and their 2006 REU
intern, Myra Stone, analyzed WIYN Tip-Tilt Module observations of the Galactic open cluster NGC
A-13
1193 and determined that the cluster is 5 Gyr old with a metallicity of [Fe/H] = –0.30 and has distance
modulus of (m-M)V = 14.12 mag with a reddening of E(B-V) = 0.21 mag. Mighell received a 3-year
grant for the proposal “Parallel-Processing Astrophysical Image-Analysis Tools” from the Applied

NASA Education and Public Outreach supplemental grant to the AISR grant was received for the
proposal “On-line Astronomical Image Analysis for Students.”
FY07 Plans
Mighell will publish a paper describing the Lost Flux Method for improving the precision of space-based
near-infrared stellar photometry with lossy detectors like Ch1 of Spitzer’s IRAC instrument. Mighell will
continue his efforts to significantly improve the precision and accuracy of stellar photometry and
astrometry from space-based, state-of-the-art cameras by enhancing the capabilities of the C-language
implementation of his MATPHOT algorithm; all code and documentation will be freely available at the
MATPHOT Web site: http://www.noao.edu/staff. Mighell, Garmany, and Fitzpatrick will start to
develop a web-based astronomy package that will allow students to remotely use computer Web services
provided by NOAO to carry out basic functions of astronomical image processing. Mighell will lead the
NOAO staff effort to write the 5-year renewal proposal for the NSF-funded KPNO Research Experiences

Research Interests
Observational cosmology and the extra-galactic distance scale; large optical/infrared telescopes; stellar
populations
Mould worked with the Spitzer MIPS team on stellar populations in the dwarf elliptical companion of
M31, NGC 205. There is increasing evidence that thick disks in galaxies provide a fossil record of an
early epoch of disk formation, involving mergers of gas-rich peer protogalaxies. To investigate these
stellar populations, Mould investigated ACS photometry of the edge-on galaxy NGC 891 in the HST
archive, finding that the thick disk is red, old, and relatively metal rich. He also worked with the Spitzer
MIPS team investigating deep galaxy counts. Mould, Ferrarese, Stetson (DAO), and others measured
Cepheid distances for NGC 5128 in order to strengthen the calibration of surface brightness fluctuations
as a standard candle.
FY07 Plans
Mould is a member of Meixner’s (STScI) team surveying the LMC with Spitzer; specifically, Mould is
part of the subgroup led by R. Blum (NOAO) studying mass loss from evolved stars. With Blum and K.
Olsen, circumstellar shells will also be sought in the Carina dwarf galaxy. To build on the HST Key
Project on the extragalactic distance scale, Mould is a member of a team that includes K. Cook and L.
Macri of NOAO to measure Cepheid distances with HST’s Advanced Camera for Surveys by finding
Cepheids in two galaxies in the Coma cluster. Mould will continue to participate in the HST COSMOS
collaboration, studying the interplay between large-scale structure, evolution, and the formation of
galaxies.
JOAN R. NAJITA, Associate Astronomer
Research Interests
Star and planet formation; wide-field surveys
A-14
In collaboration with S. Strom (NOAO) and J. Muzerolle (Steward Observatory), Najita examined the
evolutionary state of the “transition disks” being discovered by the Spitzer Space Telescope. One of the
goals of the study was to understand which, if any, of these systems are in the process of forming planets.
By examining stellar accretion rates and disk masses of transition disks, the transition disks were found
to divide into two populations: (1) a group with high disk masses and low stellar accretion rates for their
disk masses; these may have formed a Jovian mass companion; and (2) a group with low mass disks that
may be in an advanced state of photoevaporation. As a member of both the Spitzer FEPS Legacy and
IRS GTO teams studying disks around young stars, Najita contributed to several papers covering gas in
debris disks, water emission from a protostellar source, mineralogy of T Tauri star disks, and other topics.
FY07 Plans
Najita will continue to study the gas in the inner regions of planet-forming disks. A major goal is to
complete the study, with J. Carr (NRL), N. Crockett, and R. Mathieu (U. Wisconsin), of CO fundamental
emission as a probe of dissipating inner disks. A related study is on the radial filling factors of gas in
transition disks, utilizing both ground-based data and data from the Spitzer Space Telescope. With G.
Doppmann and other members of the TEXES team, Najita will be searching for hydrocarbons and other
molecules in planet-forming disks (in L-band and the mid-infrared). With S. Strom and J. Muzerolle,
Najita will also complete a census of stellar accretion rates for young stars in Taurus and IC348.

Pompea will continue his work on these ongoing projects in FY2007. AFGU will deliver its next
professional development workshop in Boston in November 2007. HOO will give workshops at Chabot
Science Center, ’Imiloa Astronomy Center of Hawaii, MESA of New Mexico, and other locales during
A-15
this year. The TLRBSE project will continue its observing and research opportunities for teachers and
students at Kitt Peak, and will extend the concept of teacher and student research through follow-up
research using the additional observing time with the Spitzer Space Telescope given in our collaboration
with the Spitzer Science Center. Pompea will continue research on developing high contrast/low stray
light imaging and spectroscopic systems and in aiding NOAO and its partners on optimizing new and
existing telescopes for better stray light performance. Pompea will be exploring some new calculations to
continue a previous project on dynamical evolution of the Earth-Moon system.

Research Interests
Infrared instrumentation for large telescopes; star formation
Probst worked as Project Scientist, Systems Engineer, and co-Project Manager (with D. Sprayberry) to
move the NEWFIRM infrared camera project into the instrument integration and test phase. Probst’s
triple role required maintaining a watchful eye on scientific performance while participating in detailed
engineering decisions and pushing to maintain schedule in the face of some technical setbacks. Probst
also worked on planning for the Science Verification observations incorporated into the instrument
commissioning period, and on defining high-impact science use in NEWFIRM’s first years of service.
FY07 Plans
Probst will lead the NEWFIRM project through first light commissioning and science verification
observing on the Mayall 4-m telescope in Semester A 2007. Science verification observations are welldefined scientific projects in galactic and extragalactic astronomy. Internal and external scientific
participants will be closely involved. These observations will produce data products in a public archive
that will have immediate scientific impact and long-term value. Probst will continue to work with the
array development, array controller, and reduction pipeline project teams within the NEWFIRM program

Research Interests
Galaxy formation and evolution; multi-wavelength star formation rate indicators; stellar populations at
high redshift; evolution of the intergalactic medium at high redshift
Reddy worked with Steidel (California Institute of Technology) and collaborators to use deep
Spitzer/MIPS images of high redshift galaxies to assess their bolometric luminosities and extinction
properties. Reddy published this work, showing that typical galaxies selected in optical surveys at
redshift z~2 are infrared luminous galaxies, and establishing a strong relationship between bolometric
luminosity and dust attenuation. In addition, Reddy published a survey paper describing a program of
rest-frame UV spectroscopy in the GOODS-North field, which included an analysis of the stellar
populations, stellar masses, ages, star formation rates, and extinction properties of galaxies at z~2–3.
FY07 Plans
Reddy will be working with M. Dickinson (NOAO) and other members of the GOODS team to study the
16- and 24-micron properties of galaxies at z~1 and z~2, respectively, to assess the evolution in the
correlation between bolometric luminosity and dust attenuation of galaxies. Quantifying this evolution
A-16
will place constraints on the number of dusty galaxies at high redshift that are missed by UV-dropout
samples at z>3, and the slope of the star formation rate density as a function of redshift for z>3. Reddy
will continue to work on simulations to quantify the incompleteness of high redshift samples of galaxies
and to assess multi-wavelength luminosity functions at z~2–4, where the bulk of the stellar mass in the
Universe was formed.

service for NOAO, he shares responsibility for oversight and management of the Adaptive Optics
Development Program activity. He worked on preparation of the NOAO proposal “Astronomical Site
Survey of the Antarctic Plateau” and on planning for future developments in optical interferometry. He
managed the optics procurement phase of a collaborative program with Subaru Telescope staff (Olivier

workshop on the “Future of Optical Interferometry,” and will continue to participate in collaborative
R&D and scientific programs.
GREGORY RUDNICK, Research Associate (Leo Goldberg Fellow)
Research Interests
Evolution of high redshift galaxies and intermediate redshift galaxy clusters
Rudnick and collaborators, I. Labbe (Carnegie Observatory), N. Foerster Schreiber (MPE), M. Franx
(Leiden Observatory), and H. W.. Rix (MPIA), measured the evolution of the volume average properties
of luminous galaxies from z=3 to z=0. They determined that the mean spectral energy distribution (SED)
of rest-frame optically luminous galaxies evolves towards redder colors with increasing time and always
looks like that of a normal galaxy from the local universe. They also determined that the stellar mass
density of the Universe declines by a factor of ~4–10 from z=3 to the present day. This was derived over
4 disjoint fields, greatly reducing the effect of their result on cosmic variance. They determined that
traditional techniques of selecting galaxies in the rest-frame Ultra-violet (observed optical) at high
redshift misses approximately 50% of the stellar mass density, highlighting the need for deep NIR
surveys. Rudnick and collaborators from the ESO Distant Cluster Survey (EDisCS) studied galaxy
clusters at 0.4<z<0.8. They used 24-micron imaging from the Spitzer telescope to measure the star
formation rates (SFRs) of the cluster galaxies and compare them to the SFRs of galaxies in the field. This
will help determine what processes terminate star formation in galaxies that enter the dense cluster
environment. They also studied the luminosity function of the cluster galaxies and found tentative
evidence for a steep faint end slope of the luminosity function, implying a large population of faint
galaxies not seen in local clusters.
A-17
FY07 Plans
Rudnick, C. Papovich (Steward Observatory), E. Le Floc’h (IfA, Hawaii), and C. Wilmer (Steward
Observatory) will conduct a large spectroscopic survey of star forming galaxies at 1.5<z<2.6. The
telescope time has been awarded and observations will be made in October and November 2006. The
goal of this project will be to constrain the redshift and obtain accurate bolometric corrections from the
observed 24-micron flux to a total Infrared luminosity (LIR). Currently, lack of spectroscopic redshifts
for these objects is one of the dominant uncertainties in determining LIR, and hence the star formation
rate. In addition to optical spectroscopy, they will obtain NIR spectroscopy with GNIRS on the Gemini
South telescope to derive SFR estimates from the Halpha emission line, which can be cross-checked
against the LIR derived SFRs. Rudnick and Jablonka (Observatoire de Sauverny) will measure the
correlations between morphological disturbance and recent star formation history (SFH) in cluster
galaxies from the EDisCS survey at 0.4<z<0.8. By determining the relative timescales with which star
formation and morphology are altered during cluster infall, they will be able to constrain the processes
that transform galaxies. Rudnick and M. Lehnert (Paris Observatory, Meudon) will use IRAC data from
Spitzer observations of EDisCS clusters to constrain the properties of cluster galaxies as well as to
measure the rest-frame optical properties of z=5 galaxies behind the EDisCS clusters that have been
spectroscopically confirmed as part of an ESO large program (PI: M. Bremer).
ABHIJIT SAHA, Astronomer
Research Interests
Variable stars; stellar populations in nearby Galaxies; distance scale; absolute calibration of Type-Ia
supernovae as distance indicators; galactic structure; assembly and star formation history in nearby
galaxies
Saha and collaborators performed a pilot study of the stellar populations in the outer limits of the
LMC/SMC complex, at distances approaching the nominal tidal radii of these objects. After
demonstrating the feasibility of their method, an NOAO survey project using the Blanco 4-m telescope
has been launched with Saha as principal investigator. Saha has participated in the investigation of
Cepheids in the extremely metal-poor galaxy IZw18. This is part of a larger context of examining the
universality of the Cepheid period-luminosity relation. Data collection for IZw18 is complete, and
analysis is in progress. A summary study of the calibration of SNeIa as standard candles using Cepheid
distances to host galaxies of nearby SNeIa has been concluded (with collaborators Sandage, Tammann
and others), with a final paper in press. Saha has also obtained data with the Gemini telescope to resolve
the controversy over the distance to a dwarf galaxy DDO 187. Analysis is in progress, and it is clear that
a definitive answer will result. In another collaboration (PI: Pritzl), data from Gemini-N is being
processed for the discovery of RR Lyrae stars in M33. The frequency of occurrence of RR Lyraes in the
disk and/or halo of M33 holds important clues to the formation of this galaxy, which appears to have had
no major mergers in its lifetime. Work is also in progress on the star formation history of the dwarf
galaxy Leo A, using data from the ACS on HST. Saha is also involved in the general retroactive
precision photometry calibration of ACS data.
FY07 Plans
The majority of Saha’s research effort will go into the NOAO “Outer Limits” Survey, which will trace
the extended structure of the LMC and SMC to distinguish between a spheroidal halo vs. an exponential
disk out at distances 7 to 15 kpc from the center. It will include a much more sensitive search for stellar
tidal debris along the Magellanic stream than has been done to date. Completion of the other ongoing
projects (described in FY06 Accomplishments) will take up the remaining efforts. Saha has participated
over the years in the development of the WFC3 camera for HST, slated for istallation in SM4 (servicing
A-18
mission 4). Assuming that SM4 will happen, Saha plans to propose for HST observations that will
exploit new capabilities that WFC3 will bring.

Samarasinha is funded through two NASA grants. He continued his studies on cometary coma
morphologies and spin evolution of asteroids and comets. Two papers, one on the colors of comets
2P/Encke and 9P/Tempel 1, and another on the Deep Impact mission target 9P/Tempel 1 were published.
Several other publications are either in review or in press. He has presented an invited talk at the third
annual Asia-Oceania Geosciences Society Meeting.
FY07 Plans
Samarasinha will continue his collaboration with S. Larson (LPL/Arizona) to characterize image
enhancement techniques and the results of this investigation will be submitted for publication. He will
continue his analysis of images of comets Machholz (C/2004 Q2) and 73P/Schwassmann-Wachmann 3.
He will submit the initial results of his investigation on how YORP torques would affect the spin states
of sub-km size asteroids for publication.
RICHARD A. SHAW, Scientist
Research Interests
Late stages of stellar evolution; planetary nebulae; Magellanic Clouds; astrophysical plasmas; stellar
populations; astronomical software and data standards
Shaw has completed a major study of Magellanic Cloud planetary nebulae (PNe) with HST imaging and
slitless spectroscopy, in collaboration with L. Stanghellini (NOAO) and E. Villaver (STScI). A recent
paper by this group on a large sample of PNe described the dimensions and morphology in several bright
emission lines, and summarized key characteristics of 149 bright PNe in the Magellanic Clouds that were
observed with HST. Trends in [O III] flux, surface brightness, and electron density with physical radius
suggested that many nebulae, particularly those with bipolar morphology, may be optically thick even at
large size. Bipolars also showed the most extreme values of [N II]/H-alpha flux ratios, which is a useful
indicator of N enrichment. The group also found that depletions of C and enhancements in N (as a result
of late-stage AGB processing) correlated strongly with nebular morphological type, as had been shown
for Galactic PNe.
The decline in [O III] surface brightness with photometric radius has recently been used to calibrate
the PN distance scale in the Galaxy. Another recent paper by this group determined masses for 21 central
stars in the LMC, which when combined with their prior survey work brings the total with reliable
masses to 37. The distribution of central star masses is non-Gaussian, and the mean mass in the sample is
slightly higher than that found in the Galaxy. This difference, if genuine, this higher average mass, can be
understood in terms of a metallicity dependency on mass-loss rates during the AGB. Since the metallicity
of the LMC is roughly half that in the Galaxy, less efficient mass loss may yield higher central star
masses for a given progenitor mass, and may lower the minimum progenitor mass required to create a
Type II supernova.
A-19
FY07 Plans
Shaw and collaborators Q. Parker and W. Reid will continue to explore the properties of a new, deep, Halpha survey of the LMC. The Reid-Parker catalog has expanded the number of known PNe in the
central LMC by a factor of nearly three. Shaw will continue his involvement in the Magellanic Cloud
Emission Line Survey (lead by C. Smith, A. Rest, S. Points, and others), which covers an area 2.5 times
larger than the RP survey LMC, and also includes a much larger area of the SMC than was explored in
the definitive survey by Jacoby & DeMarco (2002). Together, these surveys and the follow-up
spectroscopy will enable a much deeper understanding of the PN luminosity function, PN lifetimes, and
also a detailed comparison of the velocities, chemical yields, and formation history to that of younger
components of the stellar population in the Magellanic Clouds.
DAVID SILVA, Senior Scientist (Observatory Scientist, Thirty Meter Telescope)¬
Research Interests
Formation and evolution of early-type galaxies; extragalactic stellar populations; observatory operations;
end-to-end data management systems
With M. Gregg (UC-Davis) and others, Silva continued work on Next Generation Spectral Library, a
digital stellar library containing more than 300 stars in 4 metallicity bins. The core library contains HST
STIS data at 1 Angstrom resolution from 0.18–1.00 micron. Silva was PI on the Cycle 13 portion of this
project. The VLT/UVES project (Silva, PI) to build a high-resolution (R ~ 40 000) extension between
0.36 and 1.1 microns is nearly completed. With H. Kuntschner (ESO/ST-ECF) and M. Landsmann
(Imperial College, London), Silva continued a project to study the coolest stellar populations in earlytype galaxies in the Fornax cluster using near-IR imaging and spectroscopy from the ESO NTT/SOFI
and VLT/ISAAC facilities, respectively. With P. Massey, Lowell and others, Silva obtained near-IR
photometry of red super giant candidates in M31 to confront theoretical evolutionary models with
observations at higher metallicities than are possible in the Magellanic Clouds. Silva is co-advisor (with
Kuntschner) for doctoral student Mariya Lyubenova (Ludwigs-Maximilian-Universitaet, Munich,
Germany). She is studying the two-dimensional nature of the coolest populations in a small sample of
nearby ellipiticals using the AO-boosted near-IR IFU system VLT/SINFONI. This complements
analogous optical information available from the SAURON project. In combination, the optical/NIR data
should allow us to resolve age/metallicity degeneracy problems inherent in the optical data.
FY07 Plans
The first public release of the NGSL HST spectra is scheduled for December 2006. The initial UVES
data release is scheduled for early 2007. Papers with Kuntschner, Landsmann, Lyubenova, and Massey
are anticipated as those projects mature. As complement to studies of cool populations in early-type
galaxies, K-band IFU data will be obtained for a small sample of Magellanic Cloud clusters using
VLT/SINFONI (Kunstchner, PI); observations are scheduled for late 2006. Silva is also part of a team
that will be studying the cool populations of field galaxies using near-IR spectroscopy (VLT/ISAAC
time scheduled for early 2007).

Smith has continued to play a leading role in the organization and management of two large,
international NOAO survey projects: ESSENCE, which aims to constrain the equation of state of dark
energy; and SuperMACHO, which aims to constrain the location and characteristics of dark matter. Both
projects have begun to produce significant results, with over 60 supernovae discovered to date in
ESSENCE and a similar number of candidate microlensing events identified in SuperMACHO. Two
papers were submitted for publication by the ESSENCE collaboration in FY05 and two by the
SuperMACHO collaboration. Smith has also made progress toward the release of the Magellanic Cloud
Emission Line Survey (MCELS) data set for use by the astronomical community, with the “Preliminary
Data Release” at the AAS in January 2006.
FY07 Plans
Smith plans to make significant progress in mining the Magellanic Cloud Emission Line Survey
(MCELS) data set, extracting new samples of supernova remnants and planetary nebulae, and
investigating the evolution of these objects. He plans to make the second release of the MCELS data
public in early FY07. He also plans to help publish the strategy of the ESSENCE survey. In addition,
Smith will continue to develop and implement the operation plans for the Data Products Program as
several of the DPP tools come online (pipelines, archives, etc.). He will also work on providing advanced
data products from the ESSENCE and SuperMACHO surveys. Working with the development team of
LSST, Smith will support both the investigation of data processing alternatives (with experience from the
SuperMACHO and ESSENCE surveys) and operational models, including the availability of high-speed
bandwidth both from the mountain to a “base camp” downtown and from that base camp back to one or
more data centers in the continental U.S.

planetary nebulae; stellar populations; cosmic recycling
Stanghellini, Gonzales-Garcia (IAC), and Manchado (IAC) studied whether dry merging of elliptical
galaxies might account for the observed evolved stellar population in the intra-cluster space. They will
extend their theoretical investigation to include dark halos. Stanghellini, with Lee (NOAO) and Shaw
(NOAO), completed the data analysis of ACS/HST UV prism spectroscopy to obtain carbon abundances
for SMC planetary nebulae (PN). Stanghellini, with Garcia-Lario (ESA), Davies (NOAO), Shaw
(NOAO), and other collaborators, completed the analysis of Spitzer IRS spectra of LMC and SMC PN.
Stanghellini, Guerrero (Granada), Cunha (NOAO), Villaver (STScI), and Manchado reanalyzed galactic
disk PN abundances and their gradients, disclosing flatter oxygen gradients than previously detected.
FY07 Plans
Stanghellini plans to analyze cosmic recycling from low- and intermediate-mass stars and its dependence
on metallicity by studying PN abundances in a variety of environments (bulge, disk and Magellanic
Clouds). The carbon abundances of SMC PN from ACS prism spectroscopy will be published soon, and
will double the existing dataset of carbon detections in the SMC. Stanghellini and collaborators will work
on a series of papers on the IR properties of Magellanic Cloud PN as derived from the IRS Spitzer
spectra. Gas and dust content of the PN will be studied together with nebular morphology and central star
properties, to disclose possible relations between dust properties and the onset of asymmetry in PN.

Formation of stars and planetary systems
Strom (in collaboration with S. Wolff and undergraduate students L. Lanz and D. Dror) carried out a
study aimed at understanding whether low- and high-mass stars form similarly. They used the observed
projected rotational velocities among a large sample of newly formed stars spanning a range in mass
between 0.2 and 50 Msolar to search for evidence of a discontinuity in rotational properties that might
indicate a difference in the stellar formation process at some characteristic mass. Their results show that
the median of the observed rotational speed divided by equatorial breakup velocity is typically about 0.15
and shows no evidence of a discontinuity over the full range of stellar masses, while the angular
momentum per unit mass exhibits a slow, monotonic rise with increasing mass with no evidence of a
discontinuity. They argue that these observations are most simply interpreted as indicative of a single
stellar formation and angular momentum regulation mechanism, one that results in rotation rates well
below breakup and angular momenta per unit mass that differ systematically by no more than a factor of
3–4 over a mass range spanning a factor of 250.
Strom, Wolff and Dror studied the differences in the distribution of rotation speeds among young B
stars; and located in different environments: 7 low density ensembles that are destined to become
unbound stellar associations, and 8 high density ensembles that will survive as rich, bound stellar
clusters. Their results demonstrate: (1) that independent of environment, the rotation rates for stars in this
mass range do not change by more than 15% between ages 1 and 15 Myr; and (2) that stars formed in
high density regions lack the cohort of slow rotators that dominate the low density regions and young
A-22
field stars. They suggest that the differences in the distribution of rotation speeds between low and high
density regions may reflect a combination of initial conditions and environmental effects: (1) the higher
turbulent speeds that characterize molecular gas in high density, cluster-forming regions; and (2) the
stronger UV radiation fields and high stellar densities that characterize such regions. Higher turbulent
speeds may lead to higher time averaged accretion rates during the stellar assembly phase. In the context
of stellar angular momentum regulation via “disk-locking,” higher accretion rates lead to both higher
initial angular momenta and evolution-driven increases in surface rotation rates as stars contract from the
birthline to the Zero Age Main Sequence (ZAMS). Stronger UV radiation fields and higher densities may
lead to shorter disk lifetimes in cluster-forming regions. If so, B stars formed in dense clusters are more
likely to be “released” from their disks early during their PMS lifetimes and evolve into rapid rotators as
they conserve angular momentum and spin up in response to contraction. By contrast, the majority of
their brethren in low density, association forming regions can retain their disks for much or all of their
PMS lifetimes, are “locked” by their disks to rotate at constant angular speed, and lose angular
momentum as they contract toward the ZAMS, and thus arrive on the ZAMS as relatively slowly rotating
stars.
In collaboration with J. Najita and J. Muzerolle (Steward Observatory), Strom carried out a study of
the nature of transition objects: young stars with an optically thin inner accretion disk surrounded by an
optically thick outer disk. The unusual properties of these systems suggest that significant disk evolution
has occurred, possibly as a result of planet formation. To explore this possibility, they examined the
demographics of these systems, specifically the stellar accretion rates and disk masses of transition
objects compared to those of accreting T Tauri stars of comparable age. They find that transition objects
inhabit two restricted regions of the (accretion rate, disk mass) plane. Their results suggest that: (1) giant
planets may have formed in some disks, primarily those with relatively high outer disk masses; while (2)
a subset, those with the lowest outer disk masses, appear to be in an advanced state of photoevaporation.
FY07 Plans
Strom, Najita and Muzerolle plan 3 programs aimed at further assessing the properties of transition disks:
(1) a study of the accretion rates characterizing a large sample of such systems in the cluster IC 348; (2) a
study of the radial distribution of gas in selected transition objects in the Taurus-Auriga star-forming
region; and (3) a Spitzer Space Telescope study of molecular and atomic tracers sensitive to the presence
of disk gas in the radial range 1–20 astronomical units. Their goal is to evaluate which transition disks
are likely to have formed giant planets, planetesimals, or no planets at all.
Strom will continue work with Wolff on a Spitzer Space Telescope and NOAO program aimed at
quantifying the lifetimes of accretion disks surrounding intermediate mass stars and searching for
evidence of evolutionary changes from early accretion phases to the debris disk epoch. Their targets are
rich young clusters containing large numbers of B and A type pre main sequence stars.
Wolff, Strom and Dror will complete their analysis of the rotation properties of late O and early B
stars in the rich dense cluster, R 136, in the Large Magellanic Cloud in order to assess whether stellar
rotation properties in this extraordinarily dense region exhibit the bias toward rapid rotators characteristic
of B stars that are members of bound clusters in the Milky Way.

Mosaic Imagers and the NOAO Extremely Wide-Field IR Mosaic (NEWFIRM). The Mosaic pipeline
became available in FY06.
FY07 Plans
Valdes will lead efforts on NEWFIRM data handling software both at the telescope and a science
pipeline to make calibrated data available to the astronomical community. He will develop NVOoriented Web services and NVO-enabled tools. He will lead development of a new FITS standard for

Magnetic fields of sunspots; millimeter/submillimeter-wave spectroscopy of galaxies at various epochs
Walker continued directing the Project ASTRO and Family ASTRO programs as well as the ASTROChile program. She coordinated and gave Project ASTRO training workshops for teachers and their
astronomer partners in June and October 2005 and a follow-up workshop in February 2006 at David
Levy’s home-based observatory. She coordinated and gave the 4 thematic Family ASTRO workshops in
the fall of 2005 with Robert Wilson. During the year, Walker also coordinated and facilitated various
ASTRO-Chile videoconferences on remote sensing and light pollution projects between science teachers
and their students in Tucson and Chile. With the staff at GLOBE (www.globe.gov), she worked to
produce a set of Web pages called GLOBE at Night to promote social awareness of the dark sky by
measuring light pollution and submitting results on-line. Eighteen thousand people from 96 countries
contributed to a resulting world map. She organized and ran three booths on optics and light during the
three days of the annual Southern Arizona Regional Science and Engineering Fair FunFest. She cochaired the educators’ day sessions for the Optical Society of America’s annual Frontiers in Optics
conference in which there were guest speakers and optics demos for teachers and optics professionals
alike. Walker gave an invited talk on the Hands-on Optics program at the same meeting. For the third
year in a row, she co-convened three sessions at the American Geophysical Union conference on teacher
professional development programs promoting authentic science in the classroom. She and R. Sparks
developed modules for Hands-on Optics and gave many Hands-on Optics training workshops to MESA
sites and science centers around the country. Since the start of the summer 2006, Walker has been
coordinating and helping to design the Hands-on Optics programs at the Boys and Girls Clubs in Sells
and South Tucson. For the fourth year in a row, Walker has designed and given the solar research portion
of an on-line course for TLRBSE, as well as directed the solar group of teachers while on Kitt Peak for
the summer institute. She has also been in charge of the solar observing runs for the Teacher Observing
Program at the McMath-Pierce Telescope on Kitt Peak. Walker has been working on improving an ARBSE (formerly TLRBSE) project to study magnetic field strengths of sunspots using the new NSO
near-infrared array camera on the McMath-Pierce Solar Telescope. Walker has also given a number of

SIDNEY C. WOLFF, Astronomer
Research Interests
Star formation; early evolution of angular momentum; large optical/infrared telescopes; astronomy and
space science education
Wolff and Strom, working with REU students, published papers showing that the specific angular
momentum varies smoothly over the range 0.1–50 Msun, a result that suggests a common formation
mechanism (accretion through a disk rather than mergers) over this entire mass range. An analysis of the
rotation of 6–12 Msun stars shows that stars formed in high density regions lack the slow rotators that
dominate in low density association and among field stars.
FY07Plans
Observations of R136, a very high density region in the Large Magellanic Cloud, will be analyzed to
determine whether the relationship between angular momentum and density found in our own Galaxy
can be extended to an even more extreme environment. Spitzer data have been obtained to study the
evolution of disks around intermediate mass stars with ages of 1–3 million years with the goal of putting
a limit on the amount of time available for planet formation.

Abbott intends to continue his participation in the DECam collaboration and pursue upgrades to the
Blanco telescope appropriate to support this instrument and the community at large. Abbott will continue
his studies of variable stars with the ongoing analysis of a time-series-photometric pencil-beam survey
primarily intended to measure the Galactic population density of cataclysmic variables, but also as an

Research Interests
Interstellar chemistry; circumstellar disks
Boogert worked with members of the Spitzer Space Telescope Legacy team “From Molecular Cores to
Planet Forming Disks” (c2d; PI N. J. Evans II, University of Texas) on a number of projects. Results
were published on the detection of grain growth in circumstellar disks (Kessler-Silacci, et al.), and the
detection of large abundances of organic species in the inner circumstellar disk or outflow of the low
mass protostar IRS46 (Lahuis, et al.). In addition, Boogert was involved in an M-band survey of the gas
phase CO fundamental transition observed toward low mass YSOs and their disks in collaboration with
Blake, Salyk, and Brown (all at Caltech). At the high spectral resolution of the NIRSPEC (Keck II) and
Phoenix (Gemini South) instruments, many CO lines are resolved, which allows the derivation of gas
masses as a function of disk radius and evolutionary stage. Substantial gas masses were discovered in the
apparent dust gaps around several objects.
FY07 Plans
Boogert will continue to work on results from the Spitzer Space Telescope, both from the c2d legacy
team and from a 30-hour open-time program allocated last year. He will finalize a large survey of YSOs
showing absorption features due to ices, with the aim to constrain the carriers of the enigmatic 6.0- and
6.85-micron bands discovered in the 1970s. This is the first survey of its kind of low mass YSOs, and
will constrain scenarios for the formation and evolution of molecular material surrounding low mass
YSOs. The data are a combination of ground-based spectra (2–5 microns) obtained with the VLT and
Keck telescopes and Spitzer IRS spectra (5–35 microns). Boogert will also continue to work on a
ground-based M-band survey, including the search for circumstellar CH4 (in collaboration with K.
Hinkle at NOAO and G. Blake at Caltech).

Cunha and Smith analyzed Gemini high-resolution infrared spectra obtained with the Phoenix
spectrograph for a sample of K and M red giants of the galactic Bulge. They obtained a relation of [O/Fe]
versus [Fe/H] which is higher than that for the galactic disk and thick disk. The behavior of [O/Fe] is of
crucial importance in deciding between various scenarios of Galaxy formation and chemical evolution.
These results indicate that chemical evolution to metallicities higher than solar in the bulge occurred on a
rapid timescale of less than a Gyr.
FY07 Plans
Cunha’s main scientific focus will be on the analysis of high-resolution data in different stellar
populations of the Milky Way as well as dwarf galaxies. She plans to analyze infrared spectra of K and
M red giants in the galactic center and the SMC. In addition, she will put significant effort in attempting
to chemically tag samples of stars that have been identified kinematically as streams (i.e., the Sagittarius
and the galactic anti-centre streams) with the ultimate goal being to investigate the possibility of a
chemical connection with the MW populations or to abundance patterns identified in dwarf galaxies.

De Propris completed work on the Millennium Galaxy Catalogue and 2dF-SDSS LRG and QSO surveys.
His Spitzer observations of distant clusters at 0.6 < z < 1.3 showed that the mass function of galaxies is
constant and does not decrease with redshift, in severe contrast with theoretical models. De Propris
measured the merger rate of local galaxies using redshift surveys to show that this is very low. He began
comparison of this with asymmetry measurements. De Propris finished the Optical and IR catalogue of
Coma galaxies, which will be submitted to ApJS. He continued his work with PhD students in the UK

nearby clusters. He will also continue his project on the determination of accurate K-band luminosity
functions of nearby clusters with nearly complete redshift coverage from the 2dF survey. De Propris will
be submitting applications for telescope time on AAT (with UK PhD student) and Subaru. Having been

discovered a massive galaxy cluster at z = 1.45, the most distant to date. Along with Bernardi et al.,
Miller conducted an analysis of the most massive galaxies in the Universe, as well as a detailed spectral
analysis of elliptical galaxies and their environment and evolution. In collaboration with Freeman et al.,
Miller assisted in the first ever, full re-reduction of the WMAP time-stream data. They reproduced the
WMAP-team results and studied the effects that map-making techniques can have on cosmological
conclusions. Finally, Milosavljevi, Miller, Furlanetto and Cooray used the Miller et al. SDSS C4 galaxy
clusters to show that an excursion-set merger probability distribution can explain the gap in luminosities
between the brightest and second brightest galaxies in galaxy clusters.
FY07 Plans
As PI of the NOAO XCS Survey, Miller will lead a team (~20) from the U.S., England, and Portugal.
Miller will utilize the SDSS-C4 galaxy catalog to continue his research on the BCG population. He will
publish the DR5 SDSS C4 galaxy catalog, with ~2000 clusters from z = 0.03 to z = 0.2, in 8000 squaredegrees. He will produce the most detailed analysis of the cross-correlation between the galaxies and
clusters, publish an X-ray/optical analysis of Abell 1882, as well as an X-ray/optical study of a nearby
galaxy cluster with an abundance of AGN. Miller, as PI, will lead a new XMM study of fossil groups. He

well as HST/NICMOS, and demonstrated that the M31 bulge and disk are both dominated by old, nearly
solar-metallicity populations. The work was featured in a press release at the Calgary AAS meeting, was
picked up by a few news sources, was featured on the Gemini and NOAO main Web pages, and will be
described in an upcoming “GeminiFocus” article. Olsen was co-author on eight other papers published in
FY 2006, which included the discovery of dust shells around red supergiant stars, the discovery of light
echoes from ancient LMC Type Ia supernovae, the completion of an M31 and M33 photometric catalog,
and the discovery of a probable single bright AGB star with a circumstellar dust shell in the nucleus of
M31. Olsen finished the first analysis of mass-losing sources detected by Spitzer in the Carina dwarf
spheroidal, participated in several large collaborations including SuperMACHO, the Spitzer SAGE
Survey of the LMC, and the Outer Limits Survey of the LMC, and joined the ANGST collaboration to
survey nearby galaxies with HST/ACS, a project that was granted several hundred orbits of HST time.

collaboration neared completion of the process to submit two first results papers. Together with
Newman, a Research Experiences for Undergraduate (REU) student, Rest published a paper on how to
apply the NN2 technique directly to difference images in order to efficiently extract light echoes. Rest
co-authored a paper recently submitted that uses RR Lyrae stars from the LONEOS survey as probes of
the Galactic structure.
FY07 Plans
Rest will focus on publishing the first microlensing paper of the SuperMACHO project. In addition, Rest
will continue his research of SN light echoes. In particular, he and his collaborators will search for light

Ridgway plans to continue with analysis of an HST-based imaging study of the hosts of a sample of z=1
moderate luminosity radio-quiet quasars She will compare these results to existing space-based imaging
and planned ground-based adaptive optics imaging observations of samples of high z (z = 2 - 3) quasars.
Rest-frame optical-ultraviolet colors will be used to assess the star formation history of these hosts.
Through these studies, Ridgway will study the evolutionary histories of radio-quiet and radio-loud AGN
populations over a range of nuclear luminosities, and how they compare to those of other known highredshift galaxy populations. In addition, Ridgway will continue analysis of recently obtained SPITZER
IRS spectra of quasar 2s, SPITZER IRAC-color selected obscured counterparts of powerful radio-quiet
quasars. A sample of quasar 1s matched in mid-infrared luminosity were also obtained. Comparison of
the mid-infrared spectral properties of the two samples should help clarify whether the differences
between them are due primarily to obscuration of and viewing angle to the torus, or whether evolution
may also play a role.

ApJ on the observational effects of orientation on the sky on bipolar nebulae. Their study of a sample of
30 objects showed that a simple, smoothly varying dust disk model reproduced all the observed
phenomena and that equatorially concentrated disks can be excluded. Schwarz with Richards determined
star counts from Robin et al. and Soneira & Bahcall models and the USNO catalog, comparing in detail
observations with models as a function of position in the Galaxy; a paper is in preparation. This work
was commissioned by LSST to determine guide camera fields. Schwarz with Semler (REU student 2005)
finished the study of the sky brightness above Tololo based on CCD data from 1992–2006; a paper is in
preparation. Schwarz was elected President of IAU Commission 50, Vice-President of the Time
Allocation Committee of the IAC in Spain, and Chair of CTIO’s ACTR.
FY07 Plans
Schwarz intends to continue and/or finish work on all the above programs. A collaboration with Olofsson
(Sweden) will be expanded and Schwarz’ HST funds used to bring a student to CTIO to work on ESO
NTT polarimetry data on circumstellar shells around bright carbon stars. Schwarz will work on the
A-32
international time program on extinction distances to PNe with collaborators from the ING and IAC on
La Palma.
MALCOLM G. SMITH, Astronomer (Director of the AURA Observatory in Chile)
Research Interests
The early Universe; quasars/active galactic nuclei; global environmental impact of light pollution
Smith has continued his collaboration with the ChaMP group in two main areas: (a) searching for
reddened quasars, starting from hard-x-ray data obtained with Chandra and using the ISPI camera on the
Tololo 4-m, and (b) following up Chandra data using the MOSAIC 2 CCD camera as part of a
serendipitous galaxy cluster survey. He has also revived an earlier collaboration with colleagues from
Arkansas, New York, and Ohio where the group has used ISPI on the Blanco 4-m to extend this group’s
earlier optical search for high-redshift QSOs with the BTC camera on the same telescope (work which
was published in 2002). These observations are allowing the team to use z-J color to refine their lists of
optically-faint candidates (I=21.5 mag). Data reduction on two of these three projects is nearing
completion, the third is well under way.
FY07 Plans
Smith plans next to move each of his research programs from the imaging phase into a spectroscopic
follow-up phase, which will require access to 8–10-m class telescopes. In preparation for this, he is
taking a 5–6-month sabbatical leave at the University of Durham in the UK during the second half of
FY2007. Before leaving, he will use the PANIC near-IR imager on the Magellan (Baade) telescope to
contribute to the galaxy cluster survey mentioned above.
VERNE V. SMITH, Astronomer (Director, Gemini Science Center)
Research Interests
High-resolution spectroscopy; cosmochemistry; chemical evolution; stellar populations; stellar
atmospheres; stellar evolution
Smith conducted several research programs. One was determining stellar abundances in other galaxies in
the Local Group to compare chemical evolution in various galactic environments. Another was obtaining
high-resolution spectra of field red giant stars associated with tidal streams from the Sgr dwarf galaxy.
This was an initial probe of how well so-called “chemical tagging” can be used to identify distinct stellar
populations in the Galactic halo and thick disk (a precursor project to Gemini’s WFMOS). A third study
characterized the metallicity distributions in the Local Group spiral galaxy M33 as a function of
galactocentric distance by analyzing the Ca II IR-triplet lines from Gemini multi-object spectroscopy
(GMOS). A fourth study measured the lithium isotopic abundances in samples of very metal-poor halo
dwarfs to probe Big Bang Nucleosynthesis and energetic processes in the early Galactic and pre-Galactic
environments. Smith also led a small team under a JPL contract to identify stars that will be used as the
positional reference grid for the Space Interferometry Mission (SIM).
FY07 Plans
Smith will continue to pursue an active research program in cosmochemistry, as described above, with
the intent of increasing the usage of Gemini telescopes in these programs. Major new projects will
include a chemical analysis of a sample of SMC red giant spectra obtained with the Phoenix
spectrometer on the Gemini South telescope. This would be the most detailed chemical analysis of field
A-33
SMC stars to date. Smith also will conduct an abundance analysis of a sample of Galactic Center red
giants to probe chemical evolution in this poorly studied (for abundances) Galactic population. These are
also Gemini South/Phoenix spectra.
NICHOLAS B. SUNTZEFF, Astronomer (Associate Director for Science)±
ANDREI TOKOVININ, Associate Astronomer
Research Interests
Statistics and formation of binary and multiple stars; adaptive optics; site testing
Tokovinin and his colleagues published the results of the adaptive-optics survey of close spectroscopic
binaries showing that essenatially all systems with periods under 3 days are triple, while more that 1/2 of
binaries with periods longer than 10 days do not have tertiary companions. Tokovinin co-chaired the
organizing committee of the ESO Workshop “Multiple Stars Across the HR Diagram” (Garching, 2005)
and presented an update on the multiple-star statistics at this Workshop. He maintains the general catalog
of multiple stars and developed in 2005 a web-based interface to ease the access to this catalog.
As a project scientist of the SOAR Adaptive Module, Tokovinin performed detailed system analysis and
significantly contributed to the preparation of the Design Review of this instrument. Papers on the
optimization of Shack-Hartmann sensor and on the GLAO study for Gemini have been published.
Together with S. Heathcote, Tokovinin developed a new method of aberration analysis called “donut”, to
be implemented at the SOAR telescope and elsewhere. Tokovinin leads various studies related to new
methods of turbulence characterization. In 2005, he improved the data analysis algorithm of the MASS
turbulence profiler (now used extensively in the TMT site-testing program) and helped to produce
several such instruments for other observatories. He is developing new techniques for estimating the
atmospheric limits of photometry and narrow-angle astrometry, for measuring atmospheric time constant,
and for optical turbulence measurements in the ground layer.
Tokovinin’s PhD student S.Thomas has defended her thesis at the University of Nice (France) in
December 2005.
FY07 Plans
Tokovinin will continue to study various statistical properties of binary and multiple stars, providing
observational constraints for the theories of multiple-star formation. He will develop the laser guide star
sub-system for the SOAR Adaptive module, bringing it to the Design Review level. New methods of
turbulence characterization will be further studied by analytics and numerical simulation, prototyped and
tested in the field. He will continue to support the TMT site-testing activity.
NICOLE S. VAN DER BLIEK, Associate Scientist
Research Interests
Instrumentation; young stars and brown dwarfs
van der Bliek led the SOAR Adaptive Module (SAM) project through the Design Review, which was
passed successfully on December 2, 2005. The project has now moved into the detailed design and
fabrication phase. van der Bliek has continued the collaboration with B. Rodgers (Gemini Observatory)
on binarity of Herbig Ae/Be stars, a spectroscopic and photometric study of a large sample of Herbig
Ae/Be stars to detect close companions and investigate their properties. The frequency and degree of
A-34
multiplicity of HAEBE systems will provide new constraints on their formation mechanism. Other
collaborators include S. Thomas (CTIO), G. Doppmann (Gemini Observatory), J. Bouvier (Université de
Grenoble), and REU/PIA students, B. Brandvig (2005), M.J. Cordero (2006) and A. Sweet (2006).
Preliminary results include the detection of more than 60 binary candidates, of which 25 were not
previously known and there seems to be a preference for hot stars to have companions of similar mass,
while the cooler HAEBE stars (late B through F-type) seem to have even lower mass companions.
FY07 Plans
van der Bliek will continue the survey of Herbig Ae/Be stars and the search for multiples. This includes
both a continuation of the AO observations, to identify close companions, as well as a continuation of
near infrared spectroscopy to spectral type the companions and confirm physical association with the
primaries. Follow-up observations for confirmed Herbig Ae/Be binaries are being carried out at Gemini
South: 10-micron T-ReCS observations to study thermal emission of binaries containing a hot, B-type
companion; and high-resolution 2-micron spectra of binaries with a cool companion to study the
circumstellar environment. Another aspect of this project is imaging in BVRIJHK of Herbig Ae/Be stars
at lower resolution and with a slightly larger field to study clustering around these stars. The first such
data have been obtained and will be analyzed during this coming year.
ALISTAIR R. WALKER, Astronomer (Director, CTIO)
Research Interests
Stellar populations; the Magellanic Clouds; the distance scale; astronomical instrumentation
Walker was co-chair of the Science Organizing Committee for the international conference “Stellar
Pulsation and Evolution,” and edited the proceedings which have now been published. Work on several
topics presented at this meeting is being prepared for publication. This includes kinematic and stellar
population studies of the Carina dwarf spheroidal galaxy, in a collaboration with G. Bono (Rome), and
the Cepheid variables of the LMC cluster NGC 1866, with E. Brocato and G. Raimondo (Teramo).
FY07 Plans
Walker plans to continue his studies, with W. Gieren (U. Concepcion, Chile), of the stellar populations in
the galaxies in the nearby Sculptor Group, with principal aim to critically compare several distance scale
methods in a variety of environments, for which deep multi-epoch photometry has been obtained for
several galaxies using the Blanco telescope and Mosaic Imager, together with data from telescopes at La
Silla and Las Campanas. Walker expects a second project with the same collaborators, to determine
accurate light curves for a complete sample of the brighter Cepheids in the Large Magellanic Cloud, to
be completed this year. A project has been initiated to use NGC 1866 and other Magellanic Cloud
clusters as calibrators to extend the Surface Brightness Fluctuation method to younger ages, with a view
to eventually use the method to distinguish mixed populations in distant galaxies.

COMMUNITY ACCESS TO THE PRIVATE TELESCOPES
Under the Telescope System Instrumentation Program (TSIP), access to the telescopes of the major private
observatories has been expanded to include, currently: the two Keck telescopes, the HET, the MMT, and the
Magellan telescopes. However, not every one of these telescopes is available to the public in every semester,
and only about a dozen nights are available on each telescope in any given semester.

ACTIVITIES ENCOURAGING DIVERSITY
WITHIN NOAO
NOAO continues to foster, encourage, and enhance geographic, gender, ethnic, and racial diversity
among its employees in promoting astronomical research
The following includes various highlights in the AAP FY06 (08/01/2005 – 07/31/2006):
A diverse mix of 81 new staff members was hired in FY06, comprising 34 women (42%) and 13
minority group members (16%).
Women or minorities accounted for 38% of staff promotions.
In order to accommodate the particular requirements of dual-career scientific couples, NOAO
opened up two positions at the same location at NOAO South and accommodated a dual-career
scientific couple’s transfer.
We continue to update the approved policies and procedures manual for language and content
supporting increased diversity.
NOAO staff participated in job fairs, career days, and public outreach programs specifically
addressing the needs of minority group members, disadvantaged students, and the local and
nearby Native American communities.
We continued our practice of involving a diverse group of individuals in all search committees
and other recruitment practices.
We continue to provide accommodation for staff members with temporary or long-term
disabilities.
NOAO continued our affirmative action, equal employment opportunity, and Native American
preference programs as outlined in our annual Affirmative Action Plan Documents. Also, actively
recruited women and candidates from under-represented minorities with all positions.
Continued membership on the Southern Arizona Indian Workforce Development Council
(SAIWDC), an advisory body providing employment consultation as well as other programs and
activities to the Tucson Indian Center. Attending the SAIWDC quarterly meetings.
Recognizing the diversity of staff members, and understanding that family circumstances may
vary among individuals, NOAO introduced a new Domestic Partner Benefits policy to its
employees.
Staff attended a conference to enhance future recruitment for the KPNO Research Experiences for
Undergraduates (REU) NSF program.
NOAO staff participated in training programs, seminars, conferences and on-site training to
enhance the quality of employee skills.

4 QUARTER SITE SAFETY REPORT
OSHA Recordable Occupational Injuries, Illnesses, and Other Incidents
For this quarter, there were no injuries reported.
A “CryoTiger” cooling system failed in line and some of the coolant leaked into room B-38 interferometry lab”. The coolant is comprises of propane and other inert gases. The technicians
immediately evacuated the area as a precaution. After review and discussions with the
manufacturer it was determined that if the entire contents of the coolant was released an explosion
hazard would exist in a room that is less than 600 cubic feet. Therefore, where we typically use
CryoTigers there is no hazard. As an extra precaution, an oxygen sensor will be installed in this
room.
Safety and Health
Chuck Gessner officially took office in July as the President of the Southern Arizona Chapter of
the American Society of Safety Engineers (ASSE).
A preplanning safety review was conducted on July 18 for the installation of the new tertiary lock
mechanism on the WIYN telescope. Cleaning options were discussed for the MOS bearing, it was
decided to remove the bearing and use the instrument parts cleaner in Tucson to clean the bearing,
eliminating the use of solvents at the WIYN telescope.
A design and safety review meeting was conducted on July 19 for the NEWFIRM handling cart.
Several safety action items were discussed including nitrogen bottle holder, moving
considerations, forklift interface, shin guarding, cargo truck interface and others. Additional risk
management comments were made to the proposed design of the 4M cage for NEWFIRM.
A preplanning safety review was conducted at the 2.1 M telescope on July 28 in preparation for
the re-aluminizing of the primary mirror. This project was successfully completed with no safety
incidents.
Site safety reports for the 1st, 2nd, and 3rd fiscal quarters are published in the respective NOAO Quarterly Reports.

A Safety Management Review was conducted
from August 21 to 24, 2006 at the Gemini
North Observatory on the Big Island of Hawaii.
Chairing this committee was Chuck Gessner
NOAO Risk Management Specialist and
committee members included Mark J. Grushka
M.S. CSP Manager, Biosafety and Biosecurity
at the University of Arizona, Joe J. Kane
Thunder Road Consulting LLC and Steve
Shimko Keck Safety Officer. The charge given
to the Safety Review Committee was to review
several major areas:
—Specific high hazard telescope
operations
Gemini Safety Review Committee, from left to right Joe
Kane, Chuck Gessner, Mark Grushka and Steve Shimko.
—Operational and safety planning
—Compliance
—Organization and implementation of safety management
—Vehicle issues
The Gemini North Observatory has undertaken a significant process to evaluate the current
status of safety management. The Safety Review Committee was impressed by the openness of the
staff in identifying issues and sharing future plans for dealing with risks inherent in operating high
altitude telescopes. Feedback was provided by the Committee directly to presenters during each
presentation.
We celebrate the driver safety initiative being developed at Gemini South. We encourage the
organization to expand this to both sites. This approach can act as a springboard to address other
significant risks. This initiative uses a management system model, which encompasses leadership
commitment, a clearly defined implementation plan, measurable outcomes, comprehensive training
and family involvement.
The committee members are excited about the newly appointed Gemini Director Doug Simons’
intent to revitalize Gemini’s safety program and know that he will provide the leadership necessary
for success.
Doug Simons stated to his staff: “I would like to thank the review committee for sharing their
insightful, refreshing, and thought provoking perspectives on Gemini’s safety program. I learned a
lot through this process and I am confident that what you have invested in Gemini over this past
week will lead not only to important improvements in our safety program, but will help protect our
most precious resource, the lives of the Gemini staff.”
A top-level summary was presented to the Gemini Staff on the final day of the review and the
final Gemini Safety Review document was presented to Doug Simons on September 29, 2006.

4 QUARTER SITE SAFETY REPORT
Tucson and Kitt Peak elevators were inspected by Robert Brooks Certified Elevator Inspector on
September 5 and 6.
A design and safety review NEWFIRM 4M Cassegrain cage bottom meeting was conducted on
September 7.
Fire Protection and Prevention
Fire Extinguisher inspections and maintenance were provided in September at the Tucson
facilities and on Kitt Peak.
Fire Protection systems were inspection and maintained at the Tucson facilities in September.
Environmental
South West Hazard Control removed and properly disposed of 98 pounds hazardous waste and 73
pounds of non-hazardous chemical that were stored in the safety office hazardous material storage
area. NOAO will remain in the EPA classification of “Conditionally Exempt Small Quantity
Generator Status.”
South West Hazard control visited the Tucson facility to assess the work and to provide a bid to
remove asbestos containing material in the apartment building on 1015 ½ N. Martin and for the
removal of asbestos containing floor tile that was removed during the Main building floor tile
renovation.
Insurance
The AURA annual insurance renewal proposal meeting was held in Phoenix Arizona on
September 19 and 20 with George Curran (AURA), Chuck Gessner (NOAO) and Marsh insurance
broker staff. Insurance for AURA, Gemini, NOAO, WIYN, and SOAR was bound in September.
It is estimated that AURA’s overall premium cost increase about 4%. Thanks to the Center
insurance contacts for their prompt help in obtaining information for the renewal.
Security
The Tucson La Quinta HR file room is now on Keycard access; programming is complete for
authorized employees.
Keycard access to Tucson’s GROC, room 127 and room B-54 were modified for authorized
employees.
It was discovered that $149 was missing at the Tucson PAEO cash box in September. A police
report was filed, number 0609180374. Due to limited evidence, the reason for the missing money
was not determined.
