Outline of Final Research Achievements

The new detector modules, D-Egg, have been developed and fabricated to provide for the first phase of the IceCube-Gen2 experiment, an experimental instrument upgrade. After completing a large-scale operational test and modeling of the detector response, they will be buried in a deep glacier in Antarctica. In addition, we have upgraded the observation data analysis of the IceCube, which has been acquiring observation data since 2011. The accuracy of determining the arrival direction was greatly improved, and the efficiency of filtering atmospheric background was also improved. Based on this upgrade, we discovered the new neutrino source (NGC1068), analyzed the search for ultra-high energy cosmic neutrinos with the world-best sensitivity, and developed a new method of capturing neutrino emission that improves the sensitivity of the source identification by follow-up observations in the visible light and X-ray wavelength bands.

Academic Significance and Societal Importance of the Research Achievements

ニュートリノを用いた新しい宇宙物理学・天文学研究を爆発的に進展させることになった。光では暗いのにニュートリノでは明るく輝く銀河の発見、可視光の1,000兆倍ものエネルギーを持つニュートリノが宇宙から飛来していることや、それが反ニュートリノであったことを実証するなど時代を画する成果があった。将来を見据えた技術開発研究も実施した。新型高感度光検出器の開発と製作を完遂し、次世代の観測研究を開始する準備を整えた。次世代実験の建設は2025年末に南極点で行われる。またニュートリノの爆発的な放射を捉えるための解析手法の高度化も行い、この技術に基づいたニュートリノ検出アラートの運用を始める。
