"High-energy emission from GRBs and the implication for UHECRs"

X.-Y. Wang

Since the launch of Fermi satellite, more than 20 GRBs have been detected by Fermi/LAT at energies above 100 MeV, with the highest energy photon of about 30 GeV. In this talk, I will first discuss the theory on the origin of these high-energy photons, inclduing the prompt and extended high-energy photons, and its possible implication for cosmic ray acceleration. Then, I discuss hypernovae that are associated with low-luminosity GRBs as a candidate source of ultra-high energy cosmic rays.
