METALS IN THE ICM: WITNESSES OF CLUSTER FORMATION AND EVOLUTION

METALS IN THE ICM: WITNESSES OF CLUSTER FORMATION AND EVOLUTION

The baryonic composition of galaxy clusters and groups is dominated by a hot, X-ray emitting Intra-Cluster Medium (ICM). The mean metallicity of the ICM has been found to be roughly 0.3 ÷ 0.5 times the solar value, therefore a large fraction of this gas cannot be of purely primordial origin. Indeed,...
