TL;DR

This paper reports a search for high-energy neutrinos from core-collapse supernovae using 7 years of IceCube data, aiming to identify potential astrophysical sources of the diffuse neutrino flux.

Contribution

It presents a stacking analysis of IceCube data to detect neutrino emissions specifically from core-collapse supernovae, a novel approach in this context.

Findings

No significant neutrino signal detected from supernovae

Constraints placed on neutrino emission models from supernovae

Method demonstrates the potential to identify astrophysical neutrino sources

Abstract

IceCube is a cubic kilometer neutrino detector array in the Antarctic ice that was designed to search for astrophysical, high-energy neutrinos. It has detected a diffuse flux of astrophysical neutrinos that appears to be of extragalactic origin. A possible contribution to this diffuse flux could stem from core-collapse supernovae. The high-energy neutrinos could either come from the interaction of the ejecta with a dense circumstellar medium or a jet, emanating from the star's core, that stalls in the star's envelope. Here, we will present results of a stacking analysis to search for this high-energy neutrino emission from core-collapse supernovae using 7 years of $\nu_\mu$ track events from IceCube.
