Outline of Annual Research Achievements

平成29年度は、すばる望遠鏡Hyper Suprime Cam (HSC)の可視光広域撮像データと米国超大型電波干渉計(Very Large Array; VLA)の電波広域撮像データ(FIRST)
を組み合わせて電波銀河を選択する過程・手法およびその結果として得られたサンプルの基本的性質を論文にまとめて投稿した(Yamashita, Nagao, et al., submitted to the Astrophysical Journal)。
このHSC-FIRSTマッチングでは、過去のSDSS-FIRSTマッチングに比べると系統的に遠方(測光的赤方偏移で1以上)の電波銀河を選択できているが、選択された電波銀河の可視光帯での色を調べたところ、楕円銀河のようにpassive evolutionで期待されるような星種族の色よりも有意に青い天体が多いことが分かった。これは既知の低赤方偏移電波銀河がpassive evolutionと無矛盾な赤い色を示すことと対照的である。赤方偏移1は距離に換算すると80億光年近くも遠方を見ていることになり、宇宙年齢が60億年弱(現在の宇宙年齢の半分以下)の宇宙を見ていることに相当するため、青い電波銀河の割合が増加しているという結果は電波銀河の星成分が活発に形成されていた時期を捉えたと解釈することができるため、大変興味深い。
また、このHSC-FIRSTサンプルについてライマンブレイク法を適用して、120億光年以上の距離にある最遠方電波銀河も系統的に探査した。その結果、複数の候補天体を発見したため、その一部に対してジェミニ望遠鏡を用いて可視分光追求観測を敢行した。データ解析はまだ完了していないが、これまで知られていないほどの遠方にある電波銀河の発見に至る可能性が十分に期待される。
