Supermassive black holes in disk-dominated galaxies outgrow their bulgesand co-evolve with their host galaxies

Abstract: The deep connection between galaxies and their supermassive black holes iscentral to modern astrophysics and cosmology. The observed correlation betweengalaxy and black hole mass is usually attributed to the contribution of majormergers to both. We make use of a sample of galaxies whose disk-dominatedmorphologies indicate a major-merger-free history and show that such systemsare capable of growing supermassive black holes at rates similar to quasars.Comparing black hole masses to conservative upper limits on bulge masses, weshow that the black holes in the sample are typically larger than expected ifprocesses creating bulges are also the primary driver of black hole growth. Thesame relation between black hole and total stellar mass of the galaxy is foundfor the merger-free sample as for a sample which has experienced substantialmergers, indicating that major mergers do not play a significant role incontrolling the coevolution of galaxies and black holes. We suggest that morefundamental processes which contribute to galaxy assembly are also responsiblefor black hole growth.
