The Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST), with its improved sensitivity relative to previous generation gamma-ray telescopes, is significantly increasing the number of known gamma-ray sources in the sky, including pulsars. In addition to searching for gamma-ray emission from known radio pulsars, it is now possible to successfully perform blind searc...

We present an analysis of time-resolved optical emissions observed from the gamma-ray burst GRB 081126 during the prompt phase. The analysis employed time resolved photometry using optical data obtained by the TAROT telescope, using BAT data from the Swift spacecraft and time resolved spectroscopy at high energies from the GBM instrument onboard the Fermi spacecraft. The optical emission of GRB...

background: the equivalent dose in the human body due to the natural gamma-emitting radionucides (238u, 232th and 40k) in the surface soil surrounding the consolidated tin mine site in bukuru-jos, nigeria has been determined in this study. materials and methods: measurements of the soil natural radioactivity were made using a multi-channel pulseheight analyzer (canberra series 10 plus) coupled ...
