| 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.
