Search for High Energetic Neutrinos from Supernova Explosions with AMANDA

TL;DR

This study searches for high-energy neutrinos coinciding with extragalactic supernovae using the AMANDA telescope data from 2000-2006, aiming to detect neutrino emissions linked to cosmic ray acceleration.

Contribution

It introduces a likelihood-based analysis method for detecting neutrino-supernova coincidences and compiles a supernova catalogue for stacking analysis.

Findings

No significant neutrino excess detected

Enhanced sensitivity through supernova stacking

Constraints on neutrino emission from supernovae

Abstract

Supernova explosions are among the most energetic phenomena in the known universe. There are suggestions that cosmic rays up to EeV energies might be accelerated in the young supernova shell on time scales of a few weeks to years, which would lead to TeV neutrino radiation. The data taken with the AMANDA neutrino telescope in the years 2000 to 2006 is analysed with a likelihood approach in order to search for directional and temporal coincidences between neutrino events and optically observed extra-galactic supernovae. The supernovae were stacked in order to enhance the sensitivity. A catalogue of relevant core-collapse supernovae has been created. This poster presents the results from the analysis.
