Abstract
It is appropriate in a conference on the growth of galaxies to examine what we know about the evolution of galaxy sizes. Quantifying galaxy size evolution is challenging because most high-redshift galaxies are only barely resolved from the ground. The Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) has greatly improved our ability to measure the spatial structure of distant galaxies. We briefly review previous HST measurements of size evolution and present early results from analysis of the first three-fifths of the Great Observatories Origins Deep Survey (GOODS) ACS data. The observed size evolution appears to follow the basic trends expected from hierarchical models.
