Using Fermi-LAT GeV upper limits, the baryon loading factor of 12 bright GRBs is constrained to below about 10 in the standard parameter space, challenging GRBs as the dominant UHECR source.
GRB 260226A's prompt spectrum requires an extra sub-GeV component peaking near 50 MeV, with an early 5 MeV cutoff that implies a low, rising Lorentz factor if interpreted as gamma-gamma absorption.
PIC-motivated acceleration models for GRB afterglows predict a GeV-band synchrotron cutoff in low-density short GRBs that current Fermi-LAT data cannot distinguish from the Bohm limit but future observations could.
A review of extreme gamma-ray transients defined as catastrophic events or extreme particle acceleration regimes, covering diagnostics, instruments, and source classes.
