すばるとTMTの連携で拓く宇宙論
高田昌広(Kavli IPMU)

Big questions in Cosmology
天文・物理学の融合分野• ダークマターの正体‒ WIMP、原始ブラックホール、ニュートリノ質量• 宇宙の階層構造形成の物理‒ 矮小銀河、天の川銀河の構造・起源• 宇宙の初期条件（インフレーション）の物理日本の戦略：すばる+TMT• すばる = サーベイ・大統計データ
稀少天体の同定• TMT = フォローアップ観測・超高精度観測• 国際競争（特に米国、カナダ、欧米）に打ち勝
つには、すばる広視野＋TMTこそが唯一の道‒ 他国は独自の望遠鏡リソースがある
今回は宇宙論 (=大統計）のレビューというよりは、すばる+TMTで可能になる宇宙論の紹介（個人的な好み）すばるから天文学の最前線へ

まとめ （個人的見解）• すばる(大統計)＆TMT(究極高精度)は最高の組み
合わせ• 日本人独自の研究データ（すばるデータ）でTMT
でユニークなサイエンス！
• 今回の例：DMの性質、天の川銀河の起源• 今回触れなかった「通常」の宇宙論（大栗さん）‒ WL宇宙論のための Photoz較正
‒ 強重力レンズ天体(QSOs, caustic crossing) による宇宙論、
DMの性質の制限‒ 重力波宇宙論
