Title: The High Energy Telescope on EXIST Authors: J. Hong, J. E. Grindlay, B. Allen, S. D. Barthelmy, G. K. Skinner, N. Gehrels, the EXIST HET Working Group The Energetic X-ray Imaging Survey Telescope (EXIST) is a proposed next generation multi-wavelength survey mission. The primary instrumen...

Title: Close Binary Progenitors of Long Gamma Ray Bursts Authors: M.V. Barkov, S.S. Komissarov The strong dependence of the neutrino annihilation mechanism on the mass accretion rate makes it difficult to explain the LGRBs with duration in excess of 100 seconds as well as the precursors separate...

Long duration gamma-ray bursts (GRBs) seem to involve very massive stars. A new clue indicating this was uncovered recently by a series of ima...

FIU program builds cosmic ray detector For most teenagers, summer vacation and particle physics don't exactly go together. But the four high school students spending the summer at Florida International University aren't exactly most teenagers. They're working alongside nuclear physicists t...

In 2002, when astronomers first detected cosmic gamma rays — the most energetic form of light known — coming from the constellation Cygnus they were surprised and perplexed. The region lacked the extreme electromagnetic fields that they thought were required to produce such energetic rays. But n...

Scientists Prove Cosmic Rays Are Made of Protons Cosmic rays are made of protons, scientists found as they used a vast array of telescopes arranged across the Utah desert. Each telescope in the 67-unit arrangement sees the sky with a multifaceted eye. It's no wonder they call it Fly's Eye. Scientis...
