SUMMARY:Star Formation and Feedback in High-Redshift Galaxies\, Astron
 omy Colloquium\, Kristian Finlator\, UC-Santa Barbara
DESCRIPTION:The last decade has seen an explosion in observational con
 straints on galaxy growth at high redshifts (z&gt\;2).  These data off
 er a wealth of insight into fundamental questions such as the roles of
  kinetic and photoionization feedback and the relative duty cycles of 
 smooth versus bursty star formation.  Over the same period\, advances 
 in computing have enabled cosmological hydrodynamic simulations to inc
 orporate remarkably detailed treatments for galaxy growth and feedback
  processes in representative cosmological volumes.  Using comparisons 
 between predictions from these models and observations of the luminosi
 ty functions\, colors\, metallicities\, and clustering properties of y
 oung galaxies\, I will show that recent observations argue strongly in
  favor of high-redshift star formation histories that are predominantl
 y smoothly-rising and regulated by strong outflows.  I will discuss ar
 eas that are ripe for further inquiry on both theoretical and observat
 ional fronts.<br><br>
