Outline of Final Research Achievements

We systematically analyzed the X-ray spectra of many active galactic nuclei in the local universe observed with Suzaku and XMM-Newton. We have found that (1) about half of radio galaxies have ultra fast outflows, (2) the mean solid angle of tori increases with luminosity at low luminosities, and (3) a key parameter that determines AGN feedback is the Eddington ratio. By optical spectroscopic observations of ultra-luminous X-ray sources, we have revealed that they are in the supercritical accretion state, ejecting a large amount of gas via disk winds.
