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…
Bar Evolution Over the Last Eight Billion Years: A Constant Fraction of Strong Bars in GEMS
S. Jogee, F. D. Barazza, H. -W. Rix +25
One third of present-day spirals host optically visible strong bars that drive their dynamical evolution. However, the fundamental question of how bars evolve over cosmological tim…
GEMS: which galaxies dominate the z~0.7 ultraviolet luminosity density?
C. Wolf, E. F. Bell, D. H. McIntosh +14
We combine high-resolution images from GEMS with redshifts and spectral energy distributions from COMBO-17 to explore the morphological types of galaxies that dominate the z~0.7 UV…
