Distant X-ray Clusters of Galaxies: Studies and Searches
Abstract
We present the early results of a combined optical and X-ray search for distant clusters of galaxies. We imaged complete ROSAT fields, as selected from deep ROSAT exposures of extragalactic point sources with the Kitt Peak 4-meter. We have compiled a complete catalog of galaxies and clusters (using the Postman matched filter technique) and compared that cluster catalog to X-ray cluster surveys and point sources. We also present HST, ASCA, and ROSAT observations of a sample of X-ray luminous clusters of galaxies with z = 0.5-0.9.
