The Star Formation History and Stellar Assembly of High Redshift Galaxies Conference Paper uri icon

abstract

  • I discuss current observational constraints on the star-formation and stellar-assembly histories of galaxies at high redshifts. The data on massive galaxies at z < 1 implies that their stellar populations formed at z>2, and that their morphological configuration was in place soon thereafter. Spitzer Space Telescope 24 observations indicate that a substantial fraction of massive galaxies at z∼1.53 have high IR luminosities, suggesting they are rapidly forming stars, accreting material onto supermassive black holes, or both. I compare how observations of these IRactive phases in the histories of massive galaxies constrain current galaxyformation models. © 2007 International Astronomical Union.
