| Outline of Final Research Achievements |
The explosion mechanism of core-collapse supernovae (CCSNe) and the emission mechanism of the gravitational waves (GWs) is one of the long-standing riddles in astrophysics. We set the target of this research area as “deciphering the CCSN mechanism via GW detection”, then we made it to obtain the three achievements. Firstly, we performed 3D CCSN simulations including sophisticated energy-dependent neutrino transport for a garden variety of progenitors from 11.2 to 70 solar-masses with stellar rotation. This systematic study depending upon HPCI supercomputing enables us to unravel the first-ever GW emission properties not only from canonical neutron star formation, but also from black-hole formation. Secondly, based on the numerical results, we have developed novel data analysis schemes specially designed to detect these CCSN GWs. Thirdly, we have conducted the search of finding supernova GWs (albeit not detected yet), using the real data of LIGO, VIRGO, and KAGRA for the first time.
