Triangulating black hole forming stellar collapses through neutrinos

In the event of a black hole (BH) forming stellar collapse, neutrino signal should terminate abruptly at moment BH formation, after phase steady accretion. Since neutrinos are expected to reach Earth hours before electromagnetic signal, combined detection burst through multiple telescopes could allow promptly determine angular location nearby collapse in sky with high precision. this paper, we contrast triangulation pointing procedure that relies on rise time curve, often considered literature, one takes advantage cutoff curve formation. By forecasting IceCube Neutrino Observatory, Hyper-Kamiokande, and DUNE, devise strategy optimize identification curve. We show method developed by employing end tail allows achieve least order magnitude improvement precision for galactic burst, while being insensitive mixing scenario. The triangulation-pointing based will also guarantee better performance collapses occurring beyond our own Galaxy.
