Radial profiles of Fe abundance in the intracluster medium of nearby clusters observed with XMM-Newton.

MATSUSHITA K.

Abstract (from CDS):

The abundances of Fe in the intracluster medium of nearby (z<0.08) clusters were measured up to 0.3∼0.5r180. We analyzed 28 clusters of galaxies observed with XMM-Newton. We derived Fe abundances from the flux ratios of Fe lines to the continuum within an energy range of 3.5-6 keV to minimize and evaluate systematic uncertainties. The radial profiles of the Fe abundances of relaxed clusters with a cD galaxy at their X-ray peak have similar slopes. These clusters show similar enhancements in the Fe abundance within 0.1r180, and at 0.1-0.3r180, they have flatter Fe abundance profiles at 0.4∼0.5 solar, with a small scatter. Most other clusters, including merging clusters, also have similar Fe abundance profiles beyond 0.1r180. These clusters may have universal metal enrichment histories, and a significant amount of Fe was synthesized at a very early stage in cluster formation. Mergers of clusters can destroy the central Fe peak.
