Science with the Fermi Large Area Telescope

Abstract The Fermi Gamma-ray Space Telescope started its science operations in August 2008. The Large Area Telescope (LAT) is the main instrument onboard Fermi. It is an imaging, wide field-of-view pair conversion telescope able to detect photons in the energy range from about 20 MeV up to the TeV region and it is still in excellent operating conditions after 14 years of observation. The Fermi-LAT is providing an increasingly detailed portrait of the Universe’s most extraordinary phenomena and plays a crucial role in the era of multi-messenger astrophysics. A selection of the most relevant scientific results obtained by the Fermi LAT telescope and some implications from indirect searches for dark matter will be presented.
