Galaxy Evolution in Dense Environments: Properties of Interacting Galaxies in the A901/02 Supercluster
A. L. Heiderman, S. Jogee, D. J. Bacon +23
We present a study of galaxies in the STAGES survey of the Abell 901/902 supercluster at z~0.165, based on HST ACS F606W, COMBO-17, Spitzer 24um, XMM-Newton X-ray, and gravitationa…
Dry Mergers in GEMS: The Dynamical Evolution of Massive Early-Type Galaxies
Eric F. Bell, Thorsten Naab, Daniel H. McIntosh +16
We have used the 28'x 28' HST image mosaic from the GEMS (Galaxy Evolution from Morphology and SEDs) survey in conjunction with the COMBO-17 photometric redshift survey to constrai…
Integral field spectroscopy of the ultraluminous X-ray source Holmberg II X-1
I. Lehmann, T. Becker, S. Fabrika +10
We present optical integral field observations of the H II region containing the ultraluminous X-ray source Holmberg II X-1. We confirm the existence of an X-ray ionized nebula as…
Evolution and Impact of Bars over the Last Eight Billion Years: Early Results from GEMS
S. Jogee, F. D. Barazza, H. -W. Rix +24
Bars drive the dynamical evolution of disk galaxies by redistributing mass and angular momentum, and they are ubiquitous in present-day spirals. Early studies of the Hubble Deep Fi…
Evolution of optically faint AGN from COMBO-17 and GEMS
L. Wisotzki, K. Jahnke, S. F. Sanchez +13
We have mapped the AGN luminosity function and its evolution between z=1 and z=5 down to apparent magnitudes of . Within the GEMS project we have analysed HST-ACS images of m…
Colors of AGN host galaxies at 0.5<z<1.1 from GEMS
S. F. Sanchez, K. Jahnke, L. Wisotzki +13
We present the results from a study of the host galaxies of 15 optically selected AGNs with 0.5<z<1.1 from GEMS. GEMS is a Hubble Space Telescope imaging survey of a ~28"x28" conti…
UV light from young stars in GEMS quasar host galaxies at 1.8<z<2.75
K. Jahnke, S. F. Sanchez, L. Wisotzki +13
We have performed HST imaging of a sample of 23 high-redshift (1.8<z<2.75) AGN, drawn from the COMBO-17 survey. The sample contains moderately luminous quasars (M_B ~ -23). The dat…
