A Two-hump Spectrum in the Prompt Emission of GRB 240825A
An extra hard spectral component that extends to GeV energies, in additional to the typical sub-MeV Band component, appears in several gamma-ray bursts (GRBs) detected by the Fermi Large Area Telescope. Only in one case (i.e., GRB 090926A) is a spectral break feature at the high-energy end identifie...
