Assigned ID: 719 ----- Attempting Submission 1 (Fri Feb 26 22:43:19 GMT 2010) ----- The WFC3 camera on HST has allowed new measurements of the evolution of the stellar mass function and galaxy clustering as a function of stellar mass and star formation rate out to redshifts as high as z ~ 8. This theory proposal requests funding for a project to combine these new and ongoing observations with published surveys from z = 0 - 6 in order to determine galaxy star formation histories from the epoch of reionization to the present day, including a detailed treatment of uncertainties. Our method would associate galaxies with dark matter halos in a large cosmological simulation and use halo merger trees to inform the possible evolution paths of galaxies. This work would result in new constraints on the star formation rate in galaxies as a function of halo mass, galaxy environment, and redshift as well as mock catalogs of galaxies with full star formation histories which have statistically identical properties to observations. Thus, we would place a diversity of galaxy observations from HST as well as other space and ground-based telescopes into full cosmological context, connecting their stellar population histories and spatial relationships over cosmic time.
