| Outline of Final Research Achievements |
The aim of this research is to evaluate the effect of supermassive black holes on the surrounding environment by means of X-ray spectroscopy. First we used the X-ray spectrometer onboard the Hitomi satellite to find the quiescent motion of the intracluster medium of the Perseus cluster of galaxies where significant jets from the central supermassive black hole. We also utilized multi-wavelength observations that compliments X-ray data to search for distant quasars and black holes hidden behind much absorption. The absorbing matter, its relation to the evolution of super massive black holes were discussed. We also observed a "growing phase" of black hole and elucidated that the well-known relationship between black holes and their host galaxies has not yet established.

| Academic Significance and Societal Importance of the Research Achievements |
銀河の中心に存在する巨大質量ブラックホールは、銀河中心部から銀河団スケールにいたるまで周辺環境におおきな影響をおよぼしている。本研究は世界で初めて巨大ブラックホール近傍のガスと銀河団ガスの運動状態を明らかにしたもので、巨大ブラックホールと周辺への影響を理解する重要なステップである。また、高温ガスのX線性味分光データは、高温プラズマからの放射理解の基本となるもので、今後のX線分光観測への展開が期待できる。
