Outline of Final Research Achievements

We developed a cosmological analysis method that can be done by combining weak lensing information and galaxy clustering that are observed from wide-field imaging galaxy survey and spectroscopic surveys, respectively. In particular, we developed Dark Emulator that allows for fast, accurate computations of cosmological clustering quantities, using about 300TB data of N-body simulations based on machine learning. In addition, we constructed the near-infrared spectrograph camera for the Subaru Prime Focus Spectrograph project, working together with researchers from Princeton University and Johns Hopkins University.

Academic Significance and Societal Importance of the Research Achievements

宇宙の始まり、ダークマター、ダークエネルギーは、一般の関心が高い研究テーマであり、宇宙に関する人類共通の基本的な疑問である。広天域銀河分光サーベイは、これらの問題について科学的に挑むことを可能にする。一般講演会、アウトリーチなどを通して、科学に興味を持つ学生を増やすことに貢献した。また、すばる広天域多天体分光器PFSプロジェクトについては、日本が主導し、米国、ドイツ、台湾、フランス、ブラジル、中国が関与する国際共同研究で進めており、宇宙論における日本の国際的地位の確立に貢献した。PFSの装置開発については、広波長域ファイバーの技術を生み出した。
