| Outline of Final Research Achievements |
The structure of magnetosphere of a black hole is studied to understand the high-energy astrophysical phenomena in active galactic nuclei and some compact X-ray sources. Such high-energy phenomena are due to a massive black hole with magnetized plasma accretion, where the effects of strong gravity (i.e., the general relativistic effects) have a crucial role in the system around the black hole. I and collaborators make a project to detect some information about the black hole's curved spacetime by radio VLBI observation and near-infrared observation.
