Exploring the Evolution of Supermassive Black Holes in Different Environments
Abstract
Observational studies suggest that every galaxy has a supermassive black hole (BH) at its center. These studies have revealed correlations between the BH mass, and various galactic properties, such as the stellar bulge mass and dark matter halo mass. However, little is known about how the environment surrounding the host galaxy effects BH growth. We evaluate the ratio of BH mass-to-halo mass, and the ratio of BH mass-to-stellar bulge mass, for a broad collection of field, group, and cluster galaxies. We obtain the halo mass by using Chandra and XMM-Newton measurements of the hot X-ray gas in elliptical galaxies. This is used alongside measurements from the MASSIVE survey, which provides the stellar masses and BH masses of the galaxies. Combining these data will allow us to explore how BH evolution differs in galaxies with different environments, and how feedback processes regulate the growth of BHs.
