Clusters of Galaxies at z > 1
Abstract
Description
Although field galaxy studies have begun to probe the universe at z > 1, evidence for galaxy clusters at such redshifts has been sparse. New observations are accumulating rapidly, however, providing new data on the early evolution of elliptical galaxies, the blue ``Butcher-Oemler'' population, and of large scale structure at unprecedentedly large lookback times. I briefly review some of these new observations, discussing morphological and spectral characteristics of cluster galaxies at z > 1, x--ray evidence for massive, collapsed clusters out to z = 1.8, and tantalizing indications from the literature for clusters at 2 < z < 5.
