The late-time evolution of the neutrino event rate from supernovae is evaluated for SuperKamiokande using simulated results of proto–neutron star (PNS) cooling. In the present work we extend the result of Suwa et al. (2019), which studied the dependence on the PNS mass, but focus on the impact of the nuclear equation of state (EOS). We find that the neutrino event rate depends on both the high-density and low-density EOS, where the former determines the radius of the PNS and the latter affects… Expand

Neutrino Emission from Supernovae
Supernovae are the most powerful cosmic sources of MeV neutrinos. These elementary particles play a crucial role when the evolution of a massive star is terminated by the collapse of its core to aExpand
