    Abstract

    In this study, we investigate the iron core collapses systematically for various masses, especially in the range which has not been studied well so far. Here, we solve the general relativistic hydrodynamics and neutrino transfer equations simultaneously, treating neutrino reactions in detail. We also estimate the neutrino event number from the black hole formation at the Galactic center for the currently operating detectors. As a result, we suggest that the probe into the black hole progenitors is possible by detecting the neutrinos emitted from them, because the more massive the progenitor is, the softer its v̄e spectrum becomes. Further details of this study are seen in our lately submitted nanuscript [1].
