Outline of Final Research Achievements

To find direct evidence of the cosmic inflation at the beginning of the universe is one of the main topics in Cosmology. My research is focused on detecting Primordial Gravitational Waves from the cosmic inflation via B-mode signals imprinted in CMB. In this research project, I developed a data analysis pipeline of the Simons Observatory, which will be one of the most sensitive CMB experiments.

Academic Significance and Societal Importance of the Research Achievements

次世代実験であるSimons Observatoryは2023年から観測を始めるため、本研究で解析パイプラインを適応、さらに改善していくのにベストなタイミングである。将来、このパイプラインを使用して原始重力波が観測できれば、インフレーションの証拠、ひいては宇宙開闢の瞬間を観測することと同義であるため、その学術的・社会的インパクトは計り知れないと言える。
