    • Electron-positron beams from terrestrial lightning observed with fermi GBM 

      Dwyer, Joseph R.; Briggs, Michael S.; Connaughton, Valerie; Wilson-Hodge, Colleen A.; Preece, Robert D.; Fishman, Gerald Jerry; Kippen, Marc Marc; Bhat, P. Narayana; Pačiesas, William S.; Chaplin, Vandiver L. (2011-01-20)
      Terrestrial Gamma-ray Flashes (TGFs) are brief pulses of energetic radiation observed in low-earth orbit. They are associated with thunderstorms and lightning and have been observed both as gamma-ray and electron flashes ...

    • First results on terrestrial gamma ray flashes from the Fermi Gamma-ray Burst Monitor 

      Dwyer, Joseph R.; Briggs, Michael S.; Fishman, Gerald Jerry; Connaughton, Valerie; Bhat, P. Narayana; Pačiesas, William S.; Preece, Robert D.; Wilson-Hodge, Colleen A.; Chaplin, Vandiver L.; Kippen, Marc Marc (2010-07-30)
      The Gamma-ray Burst Monitor (GBM) on the Fermi Gamma-ray Space Telescope detected 12 intense terrestrial gamma ray flashes (TGFs) during its first year of observation. Typical maximum energies for most of the TGFs are ∼30 ...
