Resum:

Gamma-ray bursts are the most energetic transient events in the universe. Those with durations of a few tens of seconds are likely the result of the collapse of a massive star with high spin. A transient object, known as a collapsar, is formed: a black hole in the core of the star accreting successive layers of the stellar interior and producing two powerful twin jets. In this talk I shall briefly review the field of gamma-ray burst studies and then I'll focus on neutrino and gravitational wave production in collapsars.
