Science highlights of the Fermi-LAT

The LAT (Large Area Telescope) experiment is a gamma -ray detector onboard the Fermi satellite, sensitive to energies from 20 MeV to over 300 GeV. Launched in 2008, the main goal of the experiment is to study the origin and nature of high-energy gamma rays in the universe through the search for particle acceleration mechanisms and electromagnetic radiation emission from sources such as active galactic nuclei (AGN), pulsars, and supernova remnants, the study of galactic and extra -galactic diffuse gamma ray emission, the search for unidentified gamma -ray sources, the indirect detection of dark matter through its decay or annihilation into photons as the final state, and the study of high-energy emission from transient sources such as solar flares and gamma -ray bursts (GRBs). This contribution will illustrate the main scientific results obtained by the experiment in recent years.
