Scientific paper

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.
