Outline of Annual Research Achievements

平成28年度は、すばる望遠鏡近赤外線多天体分光装置FMOSで観測した約1100個の遠方星形成銀河のスペクトルデータを用いて、(1) 星間ガスの性質の解明と (2) 銀河のクラスタリング（集団化）の統計的性質を調べた。研究 (1) では高赤方偏移銀河の星間電離ガスが、近傍銀河に比べて、高いレベルで電離・励起されていることを明らかにし、これらの成果をまとめた論文は既にAstrophysical Journal (ApJ) 誌において出版済み（Kashino et al. 2017, ApJ, 835, 88) である。研究 (2) では、銀河を内包するハロー質量に新たな制限をつけ、銀河進化モデルを制限する手掛かりを得た。成果をまとめた論文はApJに投稿し、2017年4月現在査読中である。また、当研究代表者はこれらの成果を博士論文「The Physical Properties of Star-forming Galaxies and Their Environments at Intermediate Redshifts」(名古屋大学) として2016年8月に提出し博士（理学）を取得した。

また、関連する研究としてスローンデジタルスカイサーベイの銀河カタログを用いて、近傍銀河の金属量進化と星質量、星形成率の関係について研究を行った。これらの成果はAstrophysical Journal Letter 誌において出版済みである (Kashino et al. 2016, ApJL, 823, L24)。また、年度中から現在まで、FMOSにより得られた全ての観測データ（5500個の銀河のスペクトルデータ）のデータベースを構築を行っている。

尚、当研究代表者は2016年10月から海外の研究機関で博士研究員として採用されたため、2016年9月末をもって特別研究員を辞退した。
