Prof. Bissaldi will talk about: Probing Gamma-Ray Burst physics through high-energy observations: Current results and future perspectives.

ABSTRACT: Gamma-Ray Bursts (GRBs) represent the most powerful explosions in the Universe. Their emission, which covers the whole electromagnetic spectrum from radio to TeV energies, has been studied since the '70s by many space and ground-based observatories.
The Fermi Gamma-ray Space Telescope has been a major player in the GRB field for the past 15 years, providing unique insights into GRB physics. With thousands of GRBs detected by the Gamma-ray Burst Monitor (GBM) and hundreds by the Large Area Telescope (LAT), we have learned about the broad properties of the populations of these events and got unique insights into their emission mechanisms, environment, and physical properties.
In this seminar, I will review highlights of GRB science from low (keV) to high (GeV) energy, as well as the more recent discovery of very-high (TeV) energy GRB emission. Finally, following the historical breakthrough observation of a short GRB in coincidence with a Gravitation Wave (GW) in 2017, which paved the way into the current multimessenger era, I will focus on future prospects for space-based gamma-ray missions dedicated to GRB detections.
