Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS
COMPLETE MAPPING OF THE PERSEUS CLUSTER
ABSTRACT
We propose to observe the northern and southern region of the Perseus cluster of galaxies, which is not yet observed by ASCA, in order to complete the temperature and metal abundance map of its intracluster medium. Relation between the galaxy distribution, which is known to be elongated, and the metal abundance distribution in large scale, may lead us to the origin of the metal in the ICM. The complete temperature map will provide us the information of the distribution of dark matter, which may be an interesting issue to discuss the relation between the structure of the filament the Perseus-Pisces supercluster, where Perseus cluster itself resides.
