ABSTRACT
This is the final run of the Virgo cluster mapping project with ASCA. We propose the observations of edge regions of the Virgo cluster to look for the evidence of shocks caused by the infall of subclusters into M87 subcluster. Since the gas and darkmatter should act differently during a dynamical motion, the mass structure in the infalling subclusters will give us new knowledge on the darkmatter properties. With this mapping observation, we will almost complete the full X-ray map of the Virgo cluster. Detailed comparison of X-ray and optical structures will tell us how the Virgo cluster has evolved and acquired the present complex morphology.
