Gamma-Ray Bursts and Particle Astrophysics

TL;DR

This review discusses the fireball model of gamma-ray bursts and explores their implications for gravitational waves, neutrinos, cosmic rays, and cosmology, highlighting their significance in particle astrophysics.

Contribution

It provides a comprehensive overview of the fireball model and its consequences for multi-messenger observations and cosmological applications of gamma-ray bursts.

Findings

Gamma-ray bursts are linked to gravitational wave and neutrino production.

The fireball model explains high-energy photon emissions from bursts.

Potential use of gamma-ray bursts as standard candles for cosmology.

Abstract

Gamma-ray bursts are violent events occurring randomly in the sky. In this review, I will present the fireball model, proposed to explain the phenomenon of gamma-ray bursts. This model has important consequences for the production and observation at Earth of gravitational waves, high energy neutrinos, cosmic rays and high energy photons, and the second part of this review will be focused on these aspects. A last section will briefly discuss the topic of the use of gamma-ray bursts as standard candles and possible cosmological studies.
