Abstract: We present recent constraints on star formation rates as a function of halo mass and redshift, average star formation histories for galaxies from z=0 to z=8, and the buildup of the intracluster light as a function of halo mass and time. We also show that the universe's star formation history since z~4 can be explained by a star formation efficiency which is strongly dependent on mass but only weakly dependent on time. We discuss the impact on black hole/supernova feedback models and on the shape of the cosmic star formation rate for 0<z<8. We discuss two further applications of this work, constraining halo gas reservoir lifetimes in satellites as well as host halo properties for short gamma-ray bursts.
