Cool cores and galaxy cluster mergers
Abstract
We present the results of an Eulerian adaptive mesh refinement (AMR) hydrodynamical and N-body simulation in a λCDM cosmology carried out with the cosmological code MASCLET. The simulation incorporates common cooling and heating processes for primordial gas. The ASOHF halo finder has been applied in order to extract a sample of galaxy clusters directly obtained from the simulation without considering any resimulating scheme. We have studied the evolutionary history of the cluster haloes, and classified them into three categories depending on the merger events they have undergone. We discuss the role of merger events as a source of feedback and reheating of the ICM, and specially, their effects on the existence of cool cores in galaxy clusters, as well as in the scaling relations.
