Hard TeV Gamma-Ray Afterglows of Nearby GRB 190829A as a Tentative Signature of Ultra-high-energy Cosmic Rays Accelerated in Gamma-Ray Burst Jets
The observed hard TeV gamma-ray spectrum of the nearby gamma-ray burst (GRB) 190829A may challenge the conventional leptonic GRB afterglow model. It has been proposed that an ultra-high-energy (UHE; ${\varepsilon }_{{\rm{p}}}^{{\prime} }\sim {10}^{20}$ eV) proton population can be pre-accelerated by...
