Outline of Research at the Start

クェーサー等の活動銀河中心核(AGN)の構造は、長らく「遮蔽トーラス」を含む「現象論的描像」がパラダイムであった。しかし、この描像は物理的な裏付けが薄いなど根本的な問題があった。本研究では基礎物理過程に基づき、多次元輻射磁気流体計算を行い、全てのAGNの多波長観測に適用でき、AGNの宇宙論的進化も記述できる「新たなパラダイム」となるべき標準理論モデルを構築を目指す。 多次元輻射輸送計算による「擬似観測」によって、電波・赤外線からX線までの「全波長域」における最新観測による理論モデルの検証とモデルへのフィードバックを行う。

Outline of Annual Research Achievements

アテルイII (国立天文台) および富岳等のスーパーコンピュータを用いた理論計算を行った。X線・電波・可視・赤外線における観測との比較、そのインプットとなる輻射流体計算による巨大ブラックホール周囲の星間ガス構造を調べた。本年度に行った主な研究テーマは以下である。
1. 巨大ブラックホールから0.1 pc以内に対する高空間分解能計算により、アウトフロー構造、ダスト昇華半径構造を明らかにし、nonLTE輻射輸送計算、赤外SED計算と反響マッピングによる構造解明やBLRスペクトル計算を行い、一部の結果をAstrophysical Journalで出版した。 2.X線スペクトル計算、偏光計算を行い、Circinus galaxy等の観測データと比較し、論文を出版した。 3. 輻射輸送計算コードSKIRTによる多波長擬似観測を行った。 特にCircinus galaxyの理論モデルを改良し、ALMAおよびJWSTによるCircinus galaxyの観測等と比較した。 4. 広輝線領域の時間変動の起源を探るため、高分解能輻射流体計算をもとに、電離ガス輻射輸送コードCloudyによるスペクトル計算を行った。 5. 粒子法(ASURA)を用いて、merger-driven AGNとアウトフローの関係を調べた。

これらの研究をポスドク研究員1名や分担者とともに行った。研究代表者・分担者、関連研究者で研究打ち合わせを鹿児島大学等で行った他、随時オンラインで研究代表者で議論を行った。AGN関連の国際会議(フランス・ニース)、研究機関での談話会等で研究成果の発表と議論を行った。日本天文学会年会等で国内の研究会でも発表を行った。2023年9月にEast AGN workshopを鹿児島大学で開催し、本研究テーマに関する議論を参加者と行った。

Current Status of Research Progress
Current Status of Research Progress

1: Research has progressed more than it was originally planned.

Reason

X線から電波までの他波長域で、国際的な雑誌に多数の査読論文を出版した他、若手研究者を中心に成果を挙げている点、外国の研究者との共同研究がさまざまなテーマで進んでいる。例えば、ゲント大学(ベルギー)のグループで開発中のモンテカルロベースSKIRTコードを、ゲント大に滞在中の大学院生が改良し、われわれのAGN計算に適用し、出版した(Matsumoto et al. 2023)。 Science誌に、近傍AGNのALMA観測により、超巨大BHへ質量供給とフィードバック過程を世界で初めて明らかにした論文を発表した(Izumi et al.2023)。JWSTのプロポーザルが採択され、2024年夏の観測に向けた準備を行った(PI: 泉)。

Strategy for Future Research Activity

最近傍AGNであるCircinus galaxyのALMA観測、今後はSKIRTコードによるAGN擬似観測と観測(近傍セイファート等)との比較を行う。また、2024年7月頃にJWSTによるCircinus galaxyのわれわれの提案観測が予定されており、画期的なデータが得られることが期待できる。これらのデータに合わせて、われわれの理論モデルもさらにブラッシュアップする。2024年度は最終年度なので、研究の総括と今後の科研費申請に向けた議論を行う。
