We present a new model for the creation of cool cores in rich galaxy clusters within a LambdaCDM cosmological framework using the results from high spatial dynamic range, adaptive mesh hydro/N-body simulations. It is proposed that cores of cool gas first form in subclusters and these subclusters merge to create rich clusters with cool, central X-Ray excesses. The rich cool clusters do not possess ``cooling flows'' due to the presence of bulk velocities in the intracluster medium in excess of…

The impact of active galactic nuclei on cooling flows
This thesis explores the role of active galactic nuclei (AGN) in the heating of the intracluster medium (ICM). In the centre of many clusters the radiative cooling tune of the ICM is much shorter
