Estimations of the Distances of Stellar Collapses in the Galaxy by Analyzing the Energy Spectrum of Neutrino Bursts

TL;DR

This paper proposes a novel method to estimate the distance of galactic supernovae using only neutrino spectral data, which is useful when optical observations are unavailable.

Contribution

It introduces a new approach to determine supernova distances solely from neutrino energy spectra, relying on spectral shape and gravitational energy assumptions.

Findings

Preliminary results demonstrate the feasibility of the method.

The approach can estimate distances with reasonable accuracy.

It provides an alternative when optical data is missing.

Abstract

The neutrino telescopes of the present generation, depending on their specific features, can reconstruct the neutrino spectra from a galactic burst. Since the optical counterpart could be not available, it is desirable to have at hand alternative methods to estimate the distance of the supernova explosion using only the neutrino data. In this work we present preliminary results on the method we are proposing to estimate the distance from a galactic supernova based only on the spectral shape of the neutrino burst and assumptions on the gravitational binding energy released an a typical supernova explosion due to stellar collapses.
