Outline of Final Research Achievements

By performing the first ever systematic multi-dimensional neutrino-radiation hydrodynamics of core-collapse supernovae, we have shown that core-compactness of the progenitors is the key to diagnose the explodability of massive stars. Assuming axisymmetry of the star, our self-consistent simulations succeeded in following the long-term postbounce dynamics, about 7 s after the onset of explosion. By making a detailed analysis of the multi-messenger observables, we pointed out that Super-Kamiokande plays an essential role, for a Galactic event, in determining the epoch of core-bounce. The time-stamp of core bounce is indispensable for detecting the subsequent gravitational-wave signals that are produced by neutrino-driven convection and the shock instability in the non-linear phase. Regarding optical observation, we have done an observational drill where we have made a detailed plan for multi-wavelength observation not to miss the once-in-a-lifetime supernova event in our Milky way.
