Metal Enrichment Processes in the Intra-Cluster Medium
We present numerical simulations of galaxy clusters which include interaction processes between the galaxies and the intra-cluster gas. The considered interaction processes are galactic winds and ram-pressure stripping, which both transfer metal-enriched interstellar medium into the intra-cluster gas and hence increase its metallicity. We investigate the efficiency and time evolution of the int...
متن کاملMetal Enrichment in the Intra-cluster Medium
The enrichment of the Intra-Cluster Medium (ICM) with heavy elements is reviewed. There is now good observational evidence for enrichment including abundance ratios and metallicity distributions. Various processes involved in the enrichment process – rampressure stripping, galactic winds, galaxy-galaxy interactions, AGN outflows and intra-cluster supernovae – are described. Simulations of the I...
متن کاملSimulating the metal enrichment of the intra–cluster medium
We present results from Tree+SPH simulations of a galaxy cluster, aimed at studying the metal enrichment of the intra–cluster medium (ICM). The simulation code includes a fairly advanced treatment of star formation, as well as the release of energy feedback and detailed yields from both type-II and type-Ia supernovae, also accurately accounting for the lifetimes of different stellar populations...
متن کاملMetal Enrichment of the Intra-cluster Medium: Ram-pressure Stripping of Cluster Galaxies
We present numerical simulations of the dynamical and chemical evolution of galaxy clusters. X-ray spectra show that the intra-cluster medium contains a significant amount of metals. As heavy elements are produced in the stars of galaxies material from the galaxies must have been expelled to enrich the ambient medium. We have performed hydrodynamic simulations investigating various processes. I...
متن کاملThe Intra-Cluster Medium
The Intra-Cluster Medium (ICM) is a rarefied, hot, highly ionized, metal rich, weakly magnetized plasma. In these proceeding, after having reviewed some basic ICM properties, I discuss recent results obtained with the BeppoSAX, XMM-Newton and Chandra satellites. These results are summarized in the following five points. 1) Currently available hard X-ray data does not allow us to constrain B fie...
