The Gamma-ray Burst Monitor (GBM) is an instrument designed to detect and analyze gamma-ray bursts (GRBs), which are intense flashes of gamma rays from distant cosmic events. It is part of the Fermi Gamma-ray Space Telescope mission, launched in 2008, and helps scientists study the origins and characteristics of these powerful bursts. GBM consists of multiple detectors that cover a wide field of view, allowing it to capture GRBs from various directions. By measuring the energy and duration of these bursts, the GBM provides valuable data that contributes to our understanding of high-energy astrophysical phenomena, such as supernovae and black hole formations.
