Outline of Final Research Achievements

This research project led the data analysis of the first international joint observating run of KAGRA conducted with GEO600 in 2020, and all-sky binary neutron star searches and other analysis were done. Although no significant gravitational wave signals were found, we showed that KAGRA will be able to contribute sufficiently to astrophysics when its sensitivity is improved. A new analytical high-precision gravitational wave model incorporating the tidal deformation rate was constructed from high-precision numerical simulations of binary neutron star mergers. An independent reanalysis of GW170817's observational data was performed and provided new insights not previously known. We also worked on various other issues in gravitational wave astronomy related to neutron stars.

Academic Significance and Societal Importance of the Research Achievements

欧米以外で唯一存在する大型重力波検出器であるKAGRAの始めての国際共同観測データ観測の解析を、LIGO-Virgo-KAGRAの国際共同データ解析チームにおいて主導して行った。その結果、国際重力波検出器ネットワークの一員としてのKAGRAが、天体物理学的成果に貢献出来ることを示した。マルチメッセンジャー重力波天文学を軌道に乗せるためには、複数台の重力波検出器による同時観測が重要であり、KAGRAが国際ネットワークの一局として有効に機能できことをデータ解析の面から示したといえる重要な結果である。
