Enrichment of the Intra‐Cluster Medium Due to AGN Outflows Induced by Late‐Type Galaxies

2009 
We have investigated a transport mechanism for the enrichment of the intra‐cluster medium (ICM) due to Active Galactic Nuclei (AGN) outflows, induced by galaxy interactions. We assumed flybys and mergers of late‐type galaxies as a triggering mechanism for the AGN activity. The simulation setup of our investigations consists of a combined N‐Body/hydrodynamic technique for dark matter and the ICM and a semi‐analytical galaxy formation model. In total, we have performed eight different galaxy cluster simulations, spanning a broad mass range. The obtained metalicity maps and profiles of the ICM were compared to the maps and profiles obtained from the X‐ray observatories of different galaxy clusters. The main result is: AGN‐triggered outflows of the inter‐stellar medium (ISM) in the central parts of late‐type galaxies do not contribute significantly to the observed metalicities found in the ICM of galaxy clusters.
