| Outline of Final Research Achievements |
Elucidating the generation mechanism of jets ejected from supermassive black holes is one of the most difficult questions in astronomy. In this study, we formed a global radio telescope network jointly with East Asia including Japan, South Korea, China, and Italy, and densely monitored some nearby powerful jet sources such as M87. We obtained results suggesting a larger initial velocity than previously thought, such as detecting superluminal motion of the jet within about 20 gravitational radii from the central black hole. This implies that a black hole spin and magnetic fields play a key role in generating powerful jets, and the study overall advances the understanding of the diverse activities of supermassive black holes.
