Oscillation and Future Detection of Failed Supernova Neutrinos from Black Hole Forming Collapse

Understand

Recently, stellar collapse involving black hole formation from massive stars is suggested to emit enormous fluxes of neutrinos on par with ordinary core-collapse supernovae.

• We investigate their detectability for the currently operating neutrino detector, SuperKamiokande.
• Neutrino oscillation is also taken into account for the evaluation.
• We find that the event number is larger than or comparable to that of supernova neutrinos and, hence, black hole formation is also a candidate for neutrino astronomy.
