The Impact of cold gas accretion above a mass floor on galaxy scaling relations
N. Bouche, A. Dekel, R. Genzel +6
Using the cosmological baryonic accretion rate and normal star formation efficiencies, we present a very simple model for star-forming galaxies (SFGs) that accounts for the mass an…
High-resolution CO and radio imaging of z~2 ULIRGs: extended CO structures, and implications for the universal star formation law
M. S. Bothwell, S. C. Chapman, L. Tacconi +14
We present high spatial resolution (0.4", ~3.5 kpc) PdBI interferometric data on three ultra-luminous infrared galaxies (ULIRGs) at z~2: two submillimetre galaxies and one submilli…
[The Impact of Nuclear Star Formation on Gas Inflow to AGN
R. I. Davies, E. Hicks, M. Schartmann +8
Our adaptive optics observations of nearby AGN at spatial resolutions as small as 0.085arcsec show strong evidence for recent, but no longer active, nuclear star formation. We begi…
The orbit of the star S2 around SgrA* from VLT and Keck data
S. Gillessen, F. Eisenhauer, T. K. Fritz +5
Two recent papers (Ghez et al. 2008, Gillessen et al. 2009) have estimated the mass of and the distance to the massive black hole in the center of the Milky Way using stellar orbit…
Molecular Gas in Submillimetre-Faint, Star-Forming Ultraluminous Galaxies at z>1
C. M. Casey, S. C. Chapman, R. Neri +12
[abridged] We present interferometric CO observations of twelve z~2 submillimetre-faint, star-forming radio galaxies (SFRGs) which are thought to be ultraluminous infrared galaxies…
What is limiting near-infrared astrometry in the Galactic Center?
Tobias K. Fritz, Stefan Gillessen, Sascha Trippe +7
We systematically investigate the error sources for high-precision astrometry from adaptive optics based near-infrared imaging data. We focus on the application in the crowded stel…
A Search for Neutral Carbon towards two z=4.05 Submillimetre Galaxies, GN20 and GN20.2
C. M. Casey, S. C. Chapman, E. Daddi +15
Using the IRAM Plateau-de-Bure Interferometer (PdBI) we have searched for the upper fine structure line of neutral carbon (CI(2->1), nu_rest = 809 GHz) and 12CO(J=7->6) (nu_rest=80…
An Extremely Top-Heavy IMF in the Galactic Center Stellar Disks
H. Bartko, F. Martins, S. Trippe +19
We present new observations of the nuclear star cluster in the central parsec of the Galaxy with the adaptive optics assisted, integral field spectrograph SINFONI on the ESO/VLT. O…
A backward evolution model for infrared surveys: the role of AGN- and Color-L_TIR distributions
E. Valiante, D. Lutz, E. Sturm +2
Empirical "backward" galaxy evolution models for infrared bright galaxies are constrained using multi-band infrared surveys. We developed a new Monte-Carlo algorithm for this task,…
A Deep HST H-Band Imaging Survey of Massive Gas-Rich Mergers. II. The QUEST PG QSOs
S. Veilleux, D. -C. Kim, D. S. N. Rupke +11
We report the results from a deep HST NICMOS H-band imaging survey of 28 z < 0.3 QSOs from the Palomar-Green (PG) sample. This program is part of QUEST (Quasar / ULIRG Evolution ST…
Spitzer Quasar and ULIRG Evolution Study (QUEST). IV. Comparison of 1-Jy Ultraluminous Infrared Galaxies with Palomar-Green Quasars
S. Veilleux, D. S. N. Rupke, D. -C. Kim +16
We report the results from a comprehensive study of 74 ultraluminous infrared galaxies (ULIRGs) and 34 Palomar-Green (PG) quasars within z ~ 0.3$ observed with the Spitzer Infrared…

Understanding the Astrophysics of Galaxy Evolution: the role of spectroscopic surveys in the next decade
Eric Bell, Marc Davis, Arjun Dey +24
Over the last decade optical spectroscopic surveys have characterized the low redshift galaxy population and uncovered populations of star-forming galaxies back to z ~ 7. This work…
Evidence for X-ray synchrotron emission from simultaneous mid-IR to X-ray observations of a strong Sgr A* flare
