[161.04] Cosmological AMR Simulations of AGN Feedback and Dissipative Processes in Clusters

Recent observations show a multitude of physical effects that occur when AGN interact with the ambient ICM. An understanding of these effects is essential for all models of feedback, which is believed to be the crucial ingredient for the baryonic part of galaxy formation. We have performed a series of cosmological simulations of galaxy clusters on an adaptive mesh, which include physics that is usually neglected in these types of simulations. In particular, we include thermal conduction and viscosity. These effects are likely to play an important role in dissipating the mechanical energy of the AGN, and therefore have implications for the cooling flow problem. We also show synthetic data, showing how our simulations would appear when observed with Chandra, including the proper background and response functions.
