3C324: THE OPTICALLY-SELECTED CLUSTER CANDIDATE AT Z


ABSTRACT

3C324 is a radio galaxy located at z=1.2. There are three independent indications that this radio galaxy is in a rich cluster of galaxy; redshift of galaxies in nearby direction, the coherent shear of background galaxies, and an extended X-ray emission detected by ROSAT. With ASCA, we can determine the temperature of X-ray emission and the redshift of the hot gas, thereby we can confirm the existence of cluster and obtain a constraint on the evolution of hot gas at z=1.2.
