Abstract:
The metal-enrichment mechanism of the hot gas in clusters of galaxies is still not completely understood, particularly at large (~virial) radii where current metallicity measurements are virtually non-existent. Yet a determinaton of elemental abundances of the gas at this radius will allow us to determine which enrichment mechanism (ram pressure stripping or galactic winds) is prevalant in the outskirts of clusters. We propose a 100 kec Suzaku observation of Coma at the virial radius to determine the Fe and S abundances at this location. The ratio of these two elements will allow us to discriminate among competing models for chemical enrichment.
