Gems: The surface brightness and surface mass density evolution of disk galaxies

Abstract:

We combine HST imaging from the GEMS (Galaxy Evolution from Morphologies and SEDs) survey with photometric redshifts from COMBO-17 to explore the evolution of disk-dominated galaxies since z ≲1.1. The sample is composed of all GEMS galaxies with Sérsic indices n < 2.5, derived from fits to the galaxy images. We account fully for selection effects through careful analysis of image simulations; we are limited by the depth of the redshift and HST data to the study of galaxies with MV ≲ -20, o...
