Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS
OBSERVATION OF THE LENSING CLUSTER OF GALAXIES ABELL S295
ABSTRACTThere are mainly two methods to determine the total mass of clusters of galaxies. One is the method to use the configurations of arcs by optical observations. The other is the method to use the X-Ray observations. However, many clusters show a mass discrepancy between total masses deduced from these methods. We are interested in the cluster of galaxies Abell s295. There is no mass discrepancy in Abell s295 (Wu & Fang 1998). However, Wu & Fang estimated the X-Ray temperature from Lx-kT relation.If X-ray spectrum is available ,we can determine the temperature of the ICM observationally. Our final goal is to try to find the cause of the mass discrepancy.
