Description
The relationships between supermassive black holes (SMBHs), galaxies, and dark matter halos can reveal information about the feedback processes that regulate black hole and galaxy growth. While the SMBH-galaxy and galaxy-halo connections have been fairly well-characterized in the last two decades, the SMBH-halo connection remains less constrained. By measuring the clustering statistics of hard X-ray-selected AGN in the local universe and comparing with empirical models, we find evidence that SMBH mass correlates with host dark matter halo mass at fixed galaxy mass. This was also found using individual dynamical mass measurements of nearby galaxies, via performing a residual analyses to control for stellar mass. These results have implications for the role of AGN feedback and halo mass in regulating galaxy growth.
