Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS
ARCHEOROGY OF GALAXY CLUSTER FORMATION IN SUPERCLUSTER
ABSTRACT
We would like to propose new diagnosis with Fe K alpha line for identification of young poor clusters formed with major merging process. This method can filter only forming poor clusters. In order to confirm this diagnosis, we propose the observation of two WAT clusters A1569 and A562 with ASCA. These clusters were selected as the candidates of the merging poor clusters, which are the members of superclusters. With this observation, we can also study the hierarchical formation of galaxy clusters in superclusters.
