2018 Fiscal Year Annual Research Report

• Project/Area Number: 16H03958
• Research Institution: Ehime University
• Principal Investigator: 長尾 透 愛媛大学, 宇宙進化研究センター, 教授 (00508450)
• Project Period (FY): 2016-04-01 – 2020-03-31
• Keywords: 光学赤外線天文学 / 電波天文学 / 多波長天文学 / 銀河進化 / 巨大ブラックホール / 活動銀河中心核

Outline of Annual Research Achievements

平成30年度は、異なる成長段階にある巨大ブラックホールを有するAGNの各種族、すなわちクェーサー・電波銀河・塵に覆われたAGNについて、HSCサーベイによって新たに取得されたデータを用いて、サンプルの構築・拡張を進めた。
クェーサーについては、前年度までに赤方偏移4の光度関数を導出していたが、赤方偏移5および6についても光度関数を導出した(Matsuoka et al. 2018; Niida, Nagao, et al. submitted)。また赤方偏移7を超す(すなわち130億年以上昔の)宇宙におけるクェーサーの発見にも成功した(Matsuoka et al. 2019)。電波銀河については、HSC可視光データとFIRST電波データを組み合わせて得られる電波銀河の基本的性質を出版し(Yamashita, Nagao, et al. 2018)、このサンプルについて多波長情報を組み合わせてSEDを解析する事で星質量・星形成率・減光量といった物理量を導出した(Toba, Yamashita, Nagao, et al. submitted)。更に塵に覆われたAGNについては、塵による赤化のため可視光から赤外線にかけて極めて赤いSEDをしている一方で、可視光の短波長側だけを見ると極めて青い色を示すAGNを複数発見した(Noboriguchi, Nagao, et al., submitted)。こうした天体は、AGNの強力な放射によって銀河内の大量の塵が吹き飛ばされつつある段階に相当する可能性があり、AGNの進化モデルを観測的に検証する上で興味深い。以上の成果を広く他分野および一般の方々に報告するため、日本天文学会が発行する月刊誌である「天文月報」において総説記事を執筆した(Nagao & HSC-AGN working group, submitted)。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

本研究のゴールは、異なる巨大ブラックホールの進化段階に応じた様々なAGN種族について、すばる望遠鏡HSCの可視光データを軸とした多波長広域データを駆使することにより、サンプルの構築・拡大を進めてその統計的性質を明らかにし、巨大ブラックホールの進化について新たな知見を得ることである。このゴールとの関係で、計画3年目にあたる平成30年度には、順調にクェーサー・電波銀河・塵に覆われたAGNのそれぞれについてサンプルの構築・拡大を行うことができている。また、得られたサンプルについて基本的な統計量を導出し、複数の査読付き論文や国内外の研究集会において成果報告を行うことができている。更に、将来の多波長広域AGNサーベイを念頭に、eROSITAエックス線宇宙望遠鏡ミッションのチームとの国際共同研究体制の構築に向けた調整を順調に進めることができている。以上を踏まえると、本研究はおおむね順調に進展していると判断することが妥当であると思われる。

Strategy for Future Research Activity

平成31年度に本研究の計画最終年度を迎えるにあたり、HSCサーベイで得られる各種AGNサンプルをできるだけ拡大することにより、各種統計量についての統計精度を向上させていく。また、主に測光的情報を中心に構築してきたサンプルについて、分光観測によるスペクトル取得を進め、構築したサンプルの妥当性および分光特性に基づく各種物理量の導出を行っていく。更に、これまでに得られた統計量を統合し、巨大ブラックホールの進化という観点でどういった描像が得られるかという観点で研究の総まとめを進める。合わせて、得られた成果の論文化および国内外の研究会での報告を行い、本研究終了後のAGN探査の方向性についての展望を明らかにする。
