Outline of Annual Research Achievements

我々が開発したすばる望遠鏡用広視野カメラ (Hyper Suprime-Cam:HSC)は、2020年度末までに、予定された300晩のうち、310晩の観測を完了することができた。探査領域の広さは、当初目標の1100平方度に達成する見通しである。HSCにより取得されたデータに基づき、科学論文が多数出版されているが、これにより、日本天文学会が発行する欧文報告誌(Publication of Astronomical Society of Japan)の2020年Impact factorを前年比2倍以上の5.024(過去最高)に引き上げることに寄与できた。代表的な成果は宇宙論パラメータに新しい制限をつけたHikage et al. 2019及びHamana et al. 2020である。これは全体の1/10のデータに基づくものである。最終データでは、より強い制限が期待出来る。
新しい観測手法模索のひとつとして、新規に高速CMOS開発に取り組んでいる。量子効率及び解像度の達成に課題を残したものの、高速(10 frame/s)読み出し時において、読み出し雑音2電子という目標は達成できた。2019年度には、プロトタイプ素子を広島大学の口径1.5 mかなた望遠鏡に搭載し試験観測を行った。高速読み出し性能により、短い時間の露出が可能になった。これにより多数の短時間露出の画像を取得し、この中から、大気ゆらぎの影響が少ない画像のみを選択し、それを足し合わせることで、高解像度画像を取得することができた (Lucky Imaging)。
2020年2月にドイツで開催される国際研究会に参加を予定していたが、COVID-19の影響で延期となった。このため、旅費を繰り越したが、この研究会は2020年7月にオンライン開催された。このため、旅費をリモート会議環境整備に振り替えて使用した。
