阪大宇宙進化グループにおいては、幅広い研究が行われています。例えば、ダークマターによる構造形成と宇宙論、巨大ブラックホールと降着円盤、高エネルギー宇宙物理学、宇宙線、ジェット、銀河団、銀河形成、星形成、惑星円盤、相対論、ブラックホール・中性子星の連星合体など。我々のグループで宇宙の諸現象を研究してみたいという学生さんは、ぜひ気軽に連絡を取っていつでも訪問して下さい。
学生の皆さんへIn the Theoretical Astrophysics Group (OUTAP) at Osaka University, we pursue a wide variety of research topics, including structure formation & cosmology, high energy astrophysics, jets, accretion disks, black holes, cosmic rays, galaxy clusters, general relativity, gravitational wave, galaxy formation, star formation, proto-planetary disks, to name a few. If you are a student interested in working in our group, don't hesitate to contact & visit us anytime.
