Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS
DISTANT GALAXY CLUSTER CANDIDATE: 3C356
ABSTRACT
3C356 is a candidate of a high-z large cluster of galaxies (z=1.079). The excess number density of the galaxies and the slightly extended high X-ray emission by ROSAT/HRI suggest its existence. The luminosity with ROSAT was 2.5E44 erg/s (0.4-4keV at rest frame). This proposal is to confirm the existence of the cluster and to obtain the luminosity, the temperature and the iron abundance. The existence of the high-z clusters and their physical parameters have large effects on the evolution of the universe.
