Outline of Annual Research Achievements

本研究の目的は、次世代ガンマ線天文台であるチェレンコフ望遠鏡大規模アレイ計画Cherenkov Telescope Array (CTA)の口径23m望遠鏡LSTの4台アレイの建設を完了し、現行のガンマ線望遠鏡MAGICと合わせた観測により、高エネルギー天体の放射・粒子加速機構や宇宙線起源の解明および暗黒物質対消滅γ線探索を行うことである。本年度、以下の成果を得た。
1、(1)建設予定のLST望遠鏡2-4号基に搭載する、光電子増倍管(PMT)と波形GHzサンプリング回路からなる光検出モジュールの製作・調整を完了させ、カメラ筐体への組み上げを行った。さらに、2号基カメラの統合試験を開始した。(2)LST初号機による活動銀河核や白色矮星、天の川銀河中心領域などの科学観測を行った。
2、MAGIC望遠鏡によるTeV領域ガンマ線観測のデータを解析した。(1)巨大ブラックホール天体である電波銀河M87を電波(Event Horizon Telescope, 東アジアVLBIネットワーク)、可視、X線、ガンマ線で2017年に共同観測したデータを解析し、ガンマ線は、ブラックホール近傍の電波放射領域とは異なる場所から放射されていることが示された。(2)天の川銀河中心領域を、MAGICで、2013年から2020年まで観測し、暗黒物質質量 0.9-100 TeVの暗黒物質対消滅断面積の上限値を求め、20 TeV以上に対して従来に比べ約2倍強い制限を与えた。(3)爆発を繰り返す再帰新星RS Ophが2021年に爆発を起こし、MAGICで追観測した結果、γ線を検出した。H.E.S.S.望遠鏡による検出とともに、超高エネルギーγ線領域で再帰新星が検出された最初の観測となった。Fermi-LATとMAGICで観測されたスペクトルは、新星の衝撃波で加速された電子よりも陽子によるγ線放射の方がよく説明できた。
