Outline of Research at the Start

我々の住む銀河はどのように誕生し進化してきたのだろうか。本研究では銀河の形成・進化の研究を通して、宇宙物理学における最大の謎とされているダークマターの性質、及びコールドダークマターモデルの抱える諸問題について詳細に調査する。そのために大規模数値シミュレーションによる銀河光学化学力学進化の精密理論を構築し、高精度観測データと詳細な比較を行う。そして銀河に付随するダークマターハローに対する未解決問題である、“カスプ-コア問題”や“ミッシングサテライト問題”に代表されるコールドダークマターモデルと観測の矛盾を解明する。

Outline of Final Research Achievements

In this study, the problems facing the cold dark matter model were investigated through the study of galaxy formation and evolution. For this purpose, both cosmological and physical simulations were performed, and then we analysed the results in detail. The results were then compared with recent observational data. The galaxy evolution is precisely investigated to examine the ‘cusp-core problem’ and the ‘missing satellite problem’, which are unsolved problems for the dark matter halo.

Academic Significance and Societal Importance of the Research Achievements

我々の住む銀河はどのように誕生し進化してきたのだろうか。本研究では、銀河の形成・進化の研究を通して、宇宙物理学における最大の謎とされているダークマターの性質及びコールドダークマターモデルの抱える諸問題について詳細に調査した。また、本研究ではダークマター自身の性質のみならず、ダークマターハロー重力場中での星形成過程や超新星フィードバック過程等の天体現象を介してお互いに関連しあうため、銀河の形成・進化過程の解明にも意義を持つこととなった。
