Title: Galaxies and galaxy clusters at z > 1

Speaker: Mark Dickinson, STSci

Abstract: The universe at redshifts greater than 1 is a new frontier for the study of galaxies and galaxy clustering. Although observational surveys are not yet as systematic as those at z < 1, evidence is rapidly accumulating concerning the nature of galaxies at very high redshifts and their clustering properties. I review some recent observations of galaxies at 1 < z < 4, with an emphasis on the history of early-type galaxies (which dominate rich clusters at the present epoch), on evidence for massive clusters at 1 < z < 2, and on the roots of large-scale structure formation at z = 3.

Reference for students: Evolution of cluster galaxies at z < 1,

Galaxies and large scale structure at z=3.
