Abstract
Gamma-Ray Bursts are center stage in the new era of multimessenger astronomy, as their nature is probed through photons, gravitational waves (GW), neutrinos and cosmic rays. Discovered thanks to their powerful multiwavelength electromagnetic signal, they have been linked to the explosion of very massive stars (“long GRBs”), or to the coalescence of compact objects (“short GRBs”) which also produce a GW signal. GRBs are also believed to be efficient particle accelerators, as required by the observation of high-energy photons up to ∼ 100GeV. Therefore, quite naturally, they have been proposed as possible sources of the mysterious ultra-high-energy cosmic rays (UHECRs), with energies above 1018 eV. However, some of the current models that simultaneously produce high electromagnetic fluxes and high-energy cosmic rays necessarily produce neutrinos as well, with a flux which appears to violate the limits recently set by the IceCube detector. I will review the observational features of GRBs as multi-messenger sources, as well as their link to theoretical models.
