Outline of Final Research Achievements

In modern theoretical cosmology, the cold dark matter scenario has been successfully applied to reproduce the observed large-scale structure of the universe; this indicates that cold dark matter plays an essential role in galaxy formation. To understand the evolution of galaxies based on the cold dark matter scenario, we performed the numerical simulations that follow the evolution from the earliest stages of galaxy formation through the period of dynamical relaxation, at which point the resulting galaxy is in its final form. Our results nicely reproduce the observational characteristics in local galaxies.

Academic Significance and Societal Importance of the Research Achievements

本研究では宇宙理論と計算科学、宇宙観測といった三つの研究分野を融合し、理論と観測の融合というキーワードを念頭に、銀河形成・進化モデルの構築に取り組んだ。特に、大規模な数値シミュレーションを駆使して構築した銀河形成・進化の理論モデルと、遠方の銀河候補天体及び近傍銀河の観測データとの詳細な比較を行い、多様な銀河宇宙を解読するための基礎的な研究を行った。
