Outline of Annual Research Achievements

研究5年次となる令和3年度は、引き続き、オンチップ型超広帯域超伝導分光器という新しいコンセプトの観測装置を本格的な科学運用に投入し科学的成果を挙げることを目指として、開発を進めた。220GHzから440GHzという完全1オクターブの分光を実現するDESHIMA 2.0の製作が進み、実験室評価を実施することができた。そして、そこでの性能評価を踏まえた、実際に想定される観測感度や、それに基づく科学観測の計画を立案し、2篇の査読論文にまとめて出版することができた。大気の影響を除去するために、光軸を高速で振る（スイッチング）ための駆動機構の実装にも漕ぎ着けることができた。また、観測の際に必ず必要となる、データのクイックルックのためのシステム開発も進み、観測実施のための準備を整えることができた。装置を搭載するASTE望遠鏡の故障（副鏡駆動・制御部分の不具合）の対応が当初の想定以上に時間を要していおり、残念ながら、望遠鏡への搭載は期間内に実施することができなかったが、本格的な科学観測実施の準備が整い、その到達点をまとめた論文も出版できたことは、大きな成果である。

アルマを使った研究、特に、ハッブル宇宙望遠鏡による高感度な近赤外線観測でも見逃されていた、サブミリ波で検出される銀河種族のフォローアップ観測を進め、CO輝線あるいは[CII]輝線の検出により、分光学的赤方偏移を測定することに成功した。これらの結果に基づき、重力レンズを起こしている銀河団の質量分布モデルをさらに精密化した上で、これらの天体の物理量を測定した。近赤外線で暗くなる原因として、従来から提唱されていた「compactness」を裏付ける結果に加え、一部の天体では、銀河円盤が観測者からみて「edge-on」であり、それも一因であることがわかった。JWSTのデータもあわせた成果を複数の論文にまとめ出版することができた。
