Type IIn supernovae as sources of high energy neutrinos

TL;DR

This paper explores how Type IIn supernova remnants can produce high-energy neutrinos observed by IceCube through proton acceleration in dense circumstellar environments, modeled with nonlinear diffusive shock acceleration.

Contribution

It introduces a model linking Type IIn supernovae to high-energy neutrino production using nonlinear diffusive shock acceleration.

Findings

Type IIn supernovae can produce neutrinos detectable by IceCube.

Protons accelerated in dense circumstellar media generate high-energy neutrinos.

The nonlinear diffusive shock acceleration model effectively describes particle acceleration in these supernovae.

Abstract

It is shown that high-energy astrophysical neutrinos observed in the IceCube experiment can be produced by protons accelerated in extragalactic Type IIn supernova remnants by shocks propagating in the dense circumstellar medium. The nonlinear diffusive shock acceleration model is used for description of particle acceleration.
