Abstract: 

Gamma-Ray Bursts are intense flashes of high-energy radiation, up to a
sextillion times brighter than our sun at the peak of their emission.
They are produced by massive fastly spinning stars at the end of their
main sequence evolution, when the dying stellar core collapses into a
newly born black hole. Some bursts are also thought to produce powerful
neutrino bursts and distinctive chirps in gravitational waves. In this
talk I will introduce the physics and observations of Gamma-Ray Bursts,
discuss their role as multi-messenger objects, and describe the
accomplishments and recent advances in computer simulations of such
extreme events.
