" Co-evolution of Galactic bulges and Supermassive Black Holes "

Nozomu Kawakatu


Recent observations have revealed that the mass of a supermassive black hole (SMBH) tightly correlates with that of a galactic bulge. In addition, the downsizing of galaxies and active galactic nuclei (AGNs) have been suggested. These indicate SMBH growth is closely related to the evolution of bulges. However, little has been clear regarding the physical link between the SMBH growth and bulge evolution. In my talk, attention is focused on the extraction of angular momentum from accretion matter onto SMBHs via radiation drag exerted in a stellar bulge. Based on this mechanism, we introduce a bulge-SMBH co-evolution, and then a way to verify the SMBH growth via radiation drag with Atacama Large Millimeter Array. Finally, I will discuss the origin of AGN downsizing briefly.

Seminars are also held at JAC, CFHT, and IfA.
