Maximum Energy of Particles Accelerated in Gamma-Ray Burst Afterglow Shocks

Daniel Gro\v{s}elj, Dimitrios Giannios, Lorenzo Sironi, Paz Beniamini, Sof\'ia Guevara-Montoya, Zhao-Feng Wu

Short GRB afterglows develop a GeV synchrotron cutoff from PIC-limited electron acceleration within hours of the trigger.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

low-energy bursts in low-density environments, typical of short GRBs, exhibit a pronounced synchrotron cutoff in the GeV band within minutes to hours after the trigger

C2weakest assumption

That PIC simulation results for weakly magnetized shocks apply directly and without modification to the conditions in GRB afterglow shocks

C3one line summary

PIC-motivated acceleration in GRB afterglows produces an observable GeV synchrotron cutoff in low-density short bursts that future observations can use to distinguish from the Bohm limit.
