Outline of Final Research Achievements

In order to constrain useful constraints on neutrino mass and dark energy using large scale galaxy survey and suoernovae survey in very near future,We have developed a new meathod of measurement of galaxy shape which avoids　various systematic noises. We alos develop a new PSF correction to avoid any systematic error such as atmospheric turbulence from the first principle without employing emperical relations .We pointed out that the lensing effect of large scale structure on the magnitude-redshift relation of Type Ia supernovae can be used to constrain the nuetrino mass and dark energy parameter.

Academic Significance and Societal Importance of the Research Achievements

現在の宇宙が加速膨張をしている原因として未知の暗黒エネルギーの存在が想定されているが、その存在の観測的証拠を確立することは現代宇宙論の最も重要なテーマの一つである。またニュートリノ質量の上限の制限は、素粒子の統一理論の構成において重要な情報である。
本研究はこれらのことを念頭に近未来に実行される大規模銀河サーベイ、大規模超新星サーベイのデータに基づいて、様々な雑音を第一原理から取り除く方法を提案し、ニュートリノ質量、暗黒エネルギーについて従来よりも厳しい制限を得る方法を開発し、また新たな方法を提案してたものである。
