Obscured star formation in intermediate-density environments: A Spitzer study of the Abell 901/902 supercluster
A. Gallazzi, E. F. Bell, C. Wolf +23
We explore the amount of obscured star-formation as a function of environment in the A901/902 supercluster at z=0.165 in conjunction with a field sample drawn from the A901 and CDF…
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…
An Explanation for the Observed Weak Size Evolution of Disk Galaxies
Rachel S. Somerville, Marco Barden, Hans-Walter Rix +14
Surveys of distant galaxies with the Hubble Space Telescope and from the ground have shown that there is only mild evolution in the relationship between radial size and stellar mas…
GEMS Survey Data and Catalog
J. A. R. Caldwell, D. H. McIntosh, H-W. Rix +14
We describe the data reduction and object cataloging for the GEMS survey, a large-area (800 arcmin^2) two-band (F606W and F850LP) imaging survey with the Advanced Camera for Survey…
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…
The size evolution of galaxies since z~3: combining SDSS, GEMS and FIRES
Ignacio Trujillo, Natascha M. Forster Schreiber, Gregory Rudnick +15
We present the evolution of the luminosity-size and stellar mass-size relations of luminous (L_V>3.4x10^10h_70^-2L_sun) and of massive (M_*>3x10^10h_70^-2M_sun) galaxies in the las…
