About Fermi

Fermi is one of the NASA's great space observatory which opens a new window to observe gamma-ray sky in a high sensitivity. The Large Area Telescope (LAT) observes the gamma-rays from ~100 MeV up to 100 GeV. Another instrument, Fermi Gamma-ray Burst Monitor (Fermi-GBM), observed GRBs in 7 keV to 10 MeV.
