Supermassive Black Holes and their Feedback Effects on Galaxy Formation
Current simulations of galaxy cluster formation have difficulties in simultaneously reproducing the observed star formation rate, the temperature structure and the gas content. One possible reason for this apparent failure is the inadequate treatment of the unresolved physics close to supermassive black holes. In particular, the simplistic modeling of the energy injection of jets from active galactic nuclei (AGNs) into the surrounding gas can lead to unrealistic behavior on small scales in these simulations.
The aim of this thesis is to investigate the interaction of AGNs and their host galaxy and improve current models of accretion onto supermassive black holes and AGN feedback. Using the moving-mesh hydrodynamics code Arepo, we investigate the AGN - host galaxy connection in both, idealized high resolution simulation as well as in simulations of cosmological structure formation.
