The Subaru Seminar is
usually held in Room 104 of the Hilo Base Facility, adjacent
to the main lobby. Everyone is welcome to attend. If you are

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