Using supernova neutrinos to monitor the collapse, to search for gravity waves and to probe neutrino masses

TL;DR

This paper highlights how supernova neutrino observations can inform us about stellar collapse, aid gravitational wave detection, and help measure neutrino masses, with implications for astrophysics and fundamental physics.

Contribution

It demonstrates the use of supernova neutrino data to support explosion models, search for gravitational waves, and constrain neutrino masses, including prospects for future observations.

Findings

SN1987A neutrino data supports standard supernova explosion models.

Neutrinos can serve as triggers for gravitational wave searches.

Future galactic supernovae could measure neutrino masses below 1 eV.

Abstract

We discuss the importance of observing supernova neutrinos. By analyzing the SN1987A observations of Kamiokande-II, IMB and Baksan, we show that they provide a 2.5{\sigma} support to the standard scenario for the explosion. We discuss in this context the use of neutrinos as trigger for the search of the gravity wave impulsive emission. We derive a bound on the neutrino mass using the SN1987A data and argue, using simulated data, that a future galactic supernova could probe the sub-eV region.
