Outline of Final Research Achievements

In this work, our purpose was to uncover gaseous network, so called cosmic web, using Lyman-alpha emission as a probe, and to investigate the relation between cosmic web and galaxies. We carried out observations using VLT/MUSE, which is a sensitive optical integral field unit with a large format in FY2017 and FY 2018. ALMA was also utilized to investigate ISMs in galaxies. Finally we published a paper in Science in 2019 to report the first identification of cosmic web filaments connecting a number of galaxies and super-massive black holes. International press release was made, too.

Academic Significance and Societal Importance of the Research Achievements

宇宙においてバリオンはその大部分が銀河ではなく銀河間物質として存在しているとされる。現在の標準的な宇宙モデルでは、バリオンの大部分は銀河ではなく宇宙網(Cosmic Web)と呼ばれる蜘蛛の巣状の構造に沿って分布していると予想されている。したがって、これらの銀河と銀河を繋ぐ銀河間物質は、宇宙の構造形成、あるいは銀河進化を理解する上で欠かせない要素である。水素ライマンアルファ線をプローブとして宇宙網の観測が可能であることを立証した本研究は、今後の本格的な宇宙網探査の時代を切り拓くものだと期待される。
