Gamma-ray Astronomy with the Gamma-ray Burst Monitor on board the Fermi

Gamma-ray burst monitor (GBM) on-board the Fermi Gamma-ray Space Telescope that was launched in June 2008, was primarily designed to detect and locate Gamma-ray Bursts (GRBs) and provide complementary support to the Large Area Telescope (LAT). Fermi has been successful in studying GRBs over an unprecedented 7 decades in energy range and enabled the discovery of several hitherto unknown properties of GRBs. GBM has also been successfully used to study several Galactic gamma-ray transients using the Earth Occultation technique, long period pulsar monitoring, Solar flares and Soft Gamma-ray Repeaters (SGRs). In addition it has successfully detected a large number of Terrestrial Gamma-ray Flashes (TGFs) enhancing our knowledge of these mysterious atmospheric events significantly. We will summarize the latest results from GBM using all these techniques and also provide the latest on Gamma-ray Bursts: Standard Model of Gamma-ray Bursts, GRB Classification, GRBs and Fundamental Physics, Gamma-ray opacity of the Universe, Highlights of GBM time resolved spectroscopy, Newly discovered black-body component in GRBs and VHE counterparts of GRBs Information on the free availability of GBM data and analysis tools for young astronomers in gaining new insight into Gamma-ray astronomy will be provided.
