| Outline of Final Research Achievements |
We predicted the existence of 30 solar mass black hole (BH) binaries of the population III star origin. We showed that the origin of BH binaries can be clarified by the space gravitational wave antenna. We showed the possibility that GW 150914 is primordial BHs. We developed a code to solve the neutrino transport and showed axially symmetric supernova models that explode. We investigated the mass ejection from binary coalescence that includes a neutron star and discussed various possibilities of electromagnetic or neutrino radiation and particle acceleration. We showed the shortcoming of orbital average method in binary evolution due to Kozai mechanism and pointed out that residual eccentricity can be large. We found the existence of the graviton oscillations in bi-metric gravity and showed its observability.
We organized and co-hosted camps, public lectures and numerous international workshops, to promote the field of gravitational wave physics.
