| Abstract: |
The high-energy emission from gamma-ray bursts (GRBs) is a formidable probe of extreme physics, requiring rapid variability from highly relativistic sources. Despite the advancements in our understanding of GRBs, many fundamental questions regarding the particle acceleration and radiative processes associated with these events remain unanswered. The Large Area Telescope (LAT) onboard the Fermi satellite has been very successful in detecting the high-energy emission (>100 MeV) from Gamma-Ray Bursts (GRBs). I will present the 186 detections found by a systematic search spanning 10 years of LAT observations. We assess the characteristics of the GRB population at high energy with unprecedented sensitivity, covering aspects such as temporal properties, energetics and spectral index of the high-energy emission. By highlighting individual events, I will show how the LAT observations can be used to inform theory, and discuss the prospects for very high energy emission and the connection to gravitational waves. Finally, I will discuss the current status of the search for counterparts to gravitational wave triggers. |
