Fireballs from Superconducting Cosmic Strings

TL;DR

This paper investigates how cusp events on superconducting cosmic strings generate fireballs that emit high-energy photons and neutrinos, potentially observable as unique astrophysical signals.

Contribution

It provides a reliable estimation method for particle emission from cosmic string cusps in magnetic fields, highlighting observable signatures.

Findings

Predicts observable fluxes of high-energy photons and neutrinos from cosmic string cusps.

Identifies unique signatures that can distinguish these emissions from other astrophysical sources.

Estimates particle fluxes based on intergalactic magnetic field assumptions.

Abstract

Thermalized fireballs should be created by cusp events on superconducting cosmic strings. This simple notion allows to reliably estimate particle emission from the cusps in a given background magnetic field. With plausible assumptions about intergalactic magnetic fields, the cusp events can produce observable fluxes of high-energy photons and neutrinos with unique signatures.
