We present the recent progress of researches to clarify the phenomena of core-collapse supernovae in the light of the advance in nuclear physics. We focus on the table of equation of state (EOS), which is one of the key ingredients in supernovae, in the relativistic many body framework constrained by the data of unstable nuclei. We apply the relativistic EOS table to the numerical simulations of supernovae following the gravitational collapse of massive stars to examine whether the explosion is triggered. We discuss the influence of the EOS on the core-collapse, bounce, the revival of shock wave and the birth of proto-neutron stars. In the case of more massive stars, we demonstrate that the EOS is crucial to predict the rapid formation of black hole. The properties of neutrino burst toward the black hole formation is sensitive to the EOS accordingly and can be used as a probe of dense matter by the observation of supernova neutrinos at the terrestrial neutrino detectors.
