Multi-messenger aspects of gamma-ray bursts

Gor Oganesyan, Gran Sasso Science Institute (GSSI), Italy — Jan 16, 2022

Gamma-ray bursts were discovered in the late 60s as short erratic flashes of keV-MeV emission of unknown origin.
In the last 20 years we witnessed huge progress in understanding these phenomena thanks to the multi-wavelength space facilities and on-ground follow up. GRBs are the most energetic and extreme extragalactic transients which are produced as the consequence of the death of a class of massive stars and in the merger of binary neutron stars.
In August 2017 the first multi-messenger event including the burst signal of gravitational waves and joint electromagnetic emission has been discovered. In the last three years several very-high-energy signals (TeV) were discovered in association with long GRBs. In this talk I will summarise the current status of the multi -wavelength and the multi-messenger observations of GRBs and its applications to the high energy astrophysical phenomena. I also will talk about the future of the field, including the prospects with the next generation GW interferometers and more sensitive neutrino detectors.
