| Outline of Final Research Achievements |
In order to examine states of accretion flows onto Super Massive Black Holes (SMBHs) in Seyfert galaxies, we conducted X-ray and optical simultaneous monitoring by utilizing the Suzaku satellite and Japanese ground-based telescopes. As a result, we obtained a possibility that when the amount of materials swallowed into a SMBH is small in a Sefyert, a standard accretion disk does not reach down to an event horizon of a SMBH, and a hot accretion flow is formed like the low/hard state of black hole binaries.
In parallel, we performed ground tests of instruments onboard the Japanese X-ray satellite Hitomi. For a month after its launch, we confirmed that the almost same performance as that in ground was achieved in the orbit.
