Title: The Highest Energy Emission from Gamma-Ray Bursts
Abstract: Recent Fermi observations of GRBs show that GRB emission extends to nearly 100 GeV and no cut off in the high energy power law is observed. In fact, several GRBs exhibit a second high energy spectral component with a very hard spectrum. This high energy emission implies bulk Lorentz factors of the outflow of nearly 1000 and provide strong tests of the violation of Lorentz invariance. These observations also point to the potential for ground based observations of GRBs with the High Altitude Water Cherenkov (HAWC) observatory.
