Morphological Evolution of Galaxies from GOODS

Galaxy morphology is one of the basic observables that can be used to trace the evolution of galaxies and to constrain theories of galaxy formation. The Great Observatories Origins Deep Survey (GOODS) has used the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope to obtain deep, multiwavelength images which allows to explore the restframe optical properties of galaxies out to z > 1 in unprecedented detail. In this talk, I will provide an overview of the various analysis being done to study the morphological evolution of galaxies using GOODS. I will focus primarily on the evolution of structural parameters, the luminosity-size relation, and the space densities. I will discuss the implications of the results within the framework of hierarchical galaxy formation.
