Neutrino afterglow from Gamma-Ray Bursts: ~10^{18} eV

TL;DR

This paper predicts that gamma-ray bursts produce a significant flux of high-energy neutrinos and gamma rays in the 10^{17}-10^{19} eV range, which could be detectable if GRBs accelerate protons to ultra-high energies.

Contribution

It introduces the concept of neutrino afterglow from GRBs and estimates their energy flux and detectability, linking proton acceleration to observable high-energy particles.

Findings

GRBs can produce neutrinos and gamma rays in the 10^{17}-10^{19} eV range.

A significant fraction of GRB energy may be converted into these high-energy particles.

Detection of these particles could confirm proton acceleration to ultra-high energies in GRBs.

Abstract

We show that a significant fraction of the energy of a gamma-ray burst(GRB) is probably converted to a burst of 10^{17}-10^{19} eV neutrinos and multiple GeV gammas that follow the GRB by > 10 s . If, as previously suggested, GRB's accelerate protons to ~10^{20} eV, then both the neutrinos and the gammas may be detectable.
