MAPPING OF THE VIRGO CLUSTER: INTERACTION WITH THE M60 SUBCLUSTER AND METALLICITY GRADIENT AROUND M87
ABSTRACT
This is the 3rd run of the Virgo cluster mapping project with 3 main scientific aims. The 1st one is to obtain an evidence of interaction between M87 cluster and M60 subcluster in the form of temperature rise and metallicity variation, such as seen in M49 direction. The 2nd aim is to map out r = 1.5 deg (450 kpc) region of M87 and to trace the steep abundance gradients of Fe, Si and S out to the cluster scale. The morphological comparison between metals and galaxies should reveal the origin and process of metal injection. Finally, with this observation, we will almost complete the full X-ray map of the Virgo cluster up to 10 keV. Detailed comparison of X-ray and optical structures will tell us how Virgo cluster has evolved and acquired the present complex morphology.
