Outline of Research at the Start

最近の観測により、巨大ブラックホールと銀河がともに「ダウンサイジング」現象を示し、両者の「共進化」の描像が予想以上に複雑であることが分かりつつある。本研究は、(1)高感度の硬X線(>10 keV)観測による、合体銀河からの埋もれた活動銀河核(AGN)の探査とその宇宙論的進化の解明、(2) 広い赤方偏移・光度範囲をカバーした統合X線サンプルの多波長スペクトル解析による、AGN母銀河の進化の解明、(3) 精密X線スペクトル観測による近傍AGNの中心核構造の解明、の3 本を柱とする。これらにより、ダウンサイジングと共進化の起源について、明確な観測的検証を行なう。

Outline of Final Research Achievements

By systematically analyzing the multi-wavelength data of ultra/luminous infrared galaxies in the local Universe, we have revealed that the galaxies and supermassive black holes in their centers "co-evolve" by galaxy mergers, where AGN feedback works in the later stage. We have suggested the possibility that heavily obscured AGNs in similar populations at the more distant Universe may be missed in the current X-ray surveys. Comparing the AGN and host galaxy properties between high luminosity AGNs at z~1.5 and low luminosity ones at z=0.2-0.8, we find no evidence that their formation processes are different. We have proposed a new unified model of AGN by including polar dusty gas, in order to consistently explain the infrared and X-ray spectra of local AGNs.

Academic Significance and Societal Importance of the Research Achievements

銀河とその中心にある超大質量ブラックホール(SMBH)は、ともにダウンサイジング(小さな系ほど後で出来た)進化を示している。本研究は、銀河合体により急速に成長するAGNと、それ以外のAGNに着目して、X線・多波長データを駆使した観測的研究を行ない、両者の構造と進化に関する、共通点および相違点を明らかにした。これらの結果は、ダウンサイジングの起源を解明する上で重要な手がかりを与えるものである。
