| Outline of Final Research Achievements |
We have constructed a semi-analytic model of galaxies and active galactic nuclei (AGNs) in order to clarify their formation and evolution in the context of the cold dark matter cosmology. We have succeeded in making connection between processes of gas accretion onto supermassive black holes and spatial clustering of AGNs which is activated by the gas accretion onto the supermassive black holes. This shows that physical processes with very different spatial scales are closely related, and that we can infer the information on the black hole physics from large-scale surveys of galaxies and AGNs. Moreover we have found that we need to introduce a new timescale for gas accretion, which includes a loss of angular momentum of accreting gas, to reproduce observed luminosity functions of faint AGNs.
