Outline of Final Research Achievements

The most promising hypothesis for describing the Universe before the Big Bang is cosmic inflation, which predicts the existence of primordial gravitational waves. If observed, it would be one of the biggest scientific discoveries of all time. The only method to make this possible is observations of the polarization of the cosmic microwave background (CMB).
In this project, we successfully developed a new receiver system POLARBEAR-2, and got the first light at the beginning of 2019. We also analyzed data from observations with the POLARBEAR-1 detector system and published observation results.

Academic Significance and Societal Importance of the Research Achievements

CMB偏光を用いた観測は、科学のグランドチャレンジを行う本道であり、そのための技術開発で世界のトップレベルに立つことは将来の大発見への重要な布石である。したがって、現在のデータ解析、装置の開発の両面が大きな学術的意義をもつ。世界の中で科学のグランドチャレンジに貢献することは、我が国が国際社会の中で一目置かれる存在となることに大きく寄与する。さらに、そこで開発される新しい技術は、将来の国民の生活に資する技術の基礎となるため、大きな社会的意義をもつ。
