Scientific paper

We will talk on our evolutionary model of a supermassive black hole (SMBH) and a star formation in circumnuclear disk (CND), in which the mass-supply from a host galaxy and the physical states of CND are self-consistently considered. In the model, the turbulence excited by SN transports the angular momentum. Based on this model, we examined the physical link between the SMBH growth and different mass supply processes from host galaxies (e.g., major mergers, minor mergers, and bars). In this talk, we will show that the dispersion of final SMBH mass becomes larger as the total gas mass supplied from hosts is smaller. We will also suggest that smaller BHs grow through slower mass supply processes. Finally, we will discuss the conditions that SMBHs co-evolve with host galaxies.
