Abstract

We study the detectability of neutrino bursts from nearby direct black hole-forming collapses (failed supernovae) at Megaton (Mt) detectors. Because of their high energetics, these bursts could be identified-by the time coincidence of N2 or N3 events within a ∼1s time window-from as far as ∼4-5Mpc away. This distance encloses several supernova-rich galaxies, so that failed supernova bursts could be detected at a rate of up to one per decade, comparable to the expected rate of the more common, but less energetic, neutron star-forming collapses. Thus, the detection of a failed supernova within the lifetime of a Mt detector is realistic. It might give the first evidence of direct black hole formation, with important implications on the physics of this phenomenon.
