Outline of Research at the Start

ダークマターは存在が確実で,宇宙の星や銀河を作った立役者だが,その正体は不明である。 本領域ではダークマターの質量で90桁に亘る広大なディスカバリースペースを網羅的にカバーするため,今までにない多角的な方法で理論から宇宙観測・地上実験にまたがる研究領域を拓くことを目指す。近年急速に技術が成熟したレーザー干渉計や,すばる観測・加速器・人工衛星 ・重力波・高エネルギーニュートリノを含むタイムリーな実験・観測でダークマターに迫る。特に日本の投資による既存の最先端施設を有効活用し,若手研究者のユニークなアイディアによって工夫を加えることでインパクトの高い結果が出すことを目指す。

Outline of Final Research Achievements

We carried out a comprehensive study of dark matter. As a result, we discovered birefringence in cosmic microwave background at approximately four sigma level, which may well turn into a major discovery with follow-up observations. On the other hand, galaxy survey observations with HSC showed deviation from the standard model, which is also likely to be associated with the nature of dark matter. Both of them point to very light dark matter. As for particle-like dark matter, we developed many new theories, and we can carry out data analyses to test each of them. PFS has finally started observation with an early focus on galactic archaeology. We will report new limits on self interaction.

Academic Significance and Societal Importance of the Research Achievements

ダークマターは宇宙初期のガスを重力で引っ張り、星や銀河を作った私たちのルーツである。この正体を知ることは、人類にとっての科学的知見だけでなく、文化的に人生観にも大きな影響を与えるものである。今回の研究ではダークマターの候補を指し示す観測結果が出ており、ダークマターが今まで予想されていたよりもはるかに軽く波のように振る舞う可能性が濃厚となった。このような研究結果が日本から出ることで、若者が刺激を受けて理系に進み日本の科学技術の担い手になることも期待される。
