Multi-messenger observations of gamma-ray bursts

Abstract

As well as being amongst the most powerful objects in the Universe, Gamma Ray Bursts (GRBs) are plausible sources of the highest energy cosmic rays. Therefore GRBs are expected to be sources of high energy neutrinos. So far all searches have turned negative results, and the default models are being challenged. With the recent completion of the IceCube neutrino telescope, the question of whether GRBs are the sources of the highest energy cosmic rays will be thoroughly tested. A successful detection would enable new exciting methods to conduct astrophysical studies and complement electromagnetic observations. In this proceeedings, the prospects for positive detection with neutrino observatories will be surveyed with an emphasis on IceCube.The connection between long duration GRBs and core collapse supernovae, has led to the hypothesis that there is be a population, possibly a couple of orders of magnitudes larger than the GRB population, of so called choked GRBs. These choked GRBs are also predicted to be sources of high‐energy neutrinos. Prospects for detection by IceCube, its subdetector DeepCore and Antares will be discussed.New efforts are being pursued in following up real time neutrino alerts with optical and X‐ray telescopes. Also joint IceCube‐LIGO studies are planned. The synergy of photons, neutrinos and gravitational waves will be discussed.
