Metal distribution in the center of the Virgo cluster .
Abstract
We analyzed SUZAKU data around M87 and derived metal abundances of various elements to a radius of about 70 kpc. PSF effect and ambiguity of spectral index of the central AGN were considered. The abundances show generally positive correlation, but we do not see a significant metallicity enhancement along the extension of the NE and SW arms. This suggests that the metal lifting by radio jets may slow down around the radius of 30 kpc.
