Histories of Star Formation and Stellar Mass Assembly at High Redshift

Mark Dickinson

The size, depth, and multiwavelength coverage of deep galaxy evolution surveys have grown ever larger over the last decade, providing important observational resources for tracing the growth and evolution of galaxies at high redshift. Deep Spitzer surveys, in particular, are offering new insight into star formation and the energetics from active nuclei in distant galaxies. I will review recent progress measuring and understanding galaxy growth throughout most of cosmic history, with particular emphasis on the explosion of dust-obscured star formation and nuclear activity that seems to have made the universe a particularly interesting and exciting place at redshifts around 2.
