Institute for Advanced Study Astrophysics Seminar

Major surveys have now thoroughly sampled the galaxy population at redshifts below z ~ 1.4. This talk will summarize broadly what has been learned about galaxy evolution over these epochs, focussing on results from DEEP2 and Sloan. The main conclusion is that galaxy evolution is highly correlated with stellar mass, which in turn is plausibly correlated with halo mass. A useful working model is that galaxy evolution is driven principally by halo mass and that the star formation rate is given uniquely by halo mass at each redshift over these epochs.
