Outline of Annual Research Achievements

230GHz, 345GHz帯の超伝導受信機、及びその周波数帯域(210-375GHz)をカバーしたホーン、4-21GHz(当初予定より3GHz広い)をカバーする中間周波数(IF)帯回路、を用いて受信機システムを構築し、それぞれの周波数帯で12CO, 13CO, C18Oの合計6スペクトルの同時観測可能なシステムの実験室実験、及び、1.85m望遠鏡に搭載しての試験観測に成功した。また、望遠鏡のオーバーホール、リモート観測システムの刷新を行い、現在設置されている野辺山宇宙電波観測所での完全なリモート観測を実現している。また、TAO/MIMIZUKUのオートガイダー・シャックハルトマンセンサーに関しては、V-bandからI-band化に伴い光学系を再設計し、仕様を満たすシステム設計が完了した。MIMIZUKUの性能向上を進め、すばる望遠鏡でのファーストライトを達成し、カメラの性能向上の開発も予定通り順調である。
上記の研究・開発と平行して、様々な望遠鏡を用いた分子雲における星形成研究や、関連する理論研究を推進している。観測研究においては、ALMAを用いた大小質量星形成領域・超新星残骸の高分解能観測、45m鏡・ASTE等を用いた銀河系・系外銀河の観測、を通して、フィラメント構造を含む星形成につながる星間物質の多様性を明らかにしてきた。加えて、より遠方の渦巻銀河であるM33の巨大分子雲の詳細観測(ALMAで空間分解能1-2pcを実現)を行い、大規模星形成が分子雲同士の相互作用により引き起こされていることを明らかにした。また、理論研究においては、上記の多くの観測論文に理論的裏付けを与えるべく参加しており、星間ガスの相互作用等を通した様々な構造形成の研究も推進している。

Current Status of Research Progress

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

Reason

1.85m電波望遠鏡の広帯域化に関しては、開発の鍵となるコルゲートホーンと立体回路の広帯域化に成功した。当初予定は、中間周波数帯で4-18GHzの帯域を予定していたが、さらに3GHz広い4-21GHzの帯域の観測システムの構築に成功した。また、このシステムを用いた1.85m望遠鏡での試験観測に成功した。天体からの電波の超広帯域受信に初めて成功した事になり、将来のALMAを初めとする次世代電波望遠鏡での広帯域ヘテロダイン受信実現にむけた大きな一歩であると考えている。また、TAO/MIMIZUKUに関しても、オートガイダー・シャックハルトマンセンサーの設計、MIMIZUKUの性能向上など、順調に進んでいる。また、これらの開発と並行して、ALMAを初めとする様々な望遠鏡を用いた分子雲における星形成研究や、関連する理論研究にも大きな進展が見られた(研究実績の概要)。
望遠鏡の移設やチリ現地での作業進捗は、COVID-19の影響が大きく、現地に観測所をもつ国立天文台とも密な連携を取りつつ、その影響を注視している。現在のところ、望遠鏡のチリ移設の実現を目指して、大阪府立大学、東京大学、国立天文台、と協議を進めながら可能性を探っている。COVID-19の影響が長引くことも考慮に入れ、上記で示したように、開発・天文研究にも今まで以上に注力している(今後の研究の推進方策も参照)。

Strategy for Future Research Activity

1.85m電波望遠鏡、TAO/MIMIZUKUに関してはチリ現地での作業・オペレーションを伴うが、COVID-19の深刻な影響により、現時点では、手続き、現地作業はかなり困難な状況である。状況が治まり次第直ちに再開するが、航空機での渡航の制限や船貨物便の逼迫・高騰化などしばらくは困難な状態が継続する可能性もある。このような場合は、例えば、1.85m望遠鏡の場合は、日本での搭載試験、場合によっては観測も推進し、移設後の立ち上げ作業の最小化を目指す。また、次世代ALMAに向けての超広帯域受信機システムのさらなる広帯域化、低雑音化等を推進する可能性もあるが、これらの開発も平行して行いつつ、現段階では、チリへの早期移設・観測実現を目指している。このような状況の中、様々な望遠鏡を用いた分子雲における星形成研究、関連する理論研究も強力に推進しており、望遠鏡の移設などが難しい場合は、研究員を雇用するなど、さらに強化する可能性も考えている。また、南天での分子雲観測を補完するため、同じくチリ・アタカマに設置されたASTE やNANTEN2の運用・機能強化等への積極的な参加も考慮したい。
