Overview

Observational analysis reveals scale-invariant self-organized criticality in the prompt emission pulses of GRB 230307A, suggesting magnetic energy dissipation powers ultrarelativistic jets.

Key Points

To determine whether the prompt emission of gamma-ray bursts is driven by kinetic or magnetic energy dissipation by evaluating pulse distributions in GRB 230307A.
Analyzed prompt emission pulse data from the exceptionally bright GRB 230307A recorded by the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM).
Calculated cumulative distributions of pulse peak counts, pulse durations, and inter-pulse waiting times to assess scale invariance against self-organized criticality theory.
Identified scale-invariant cumulative distributions across peak counts, pulse durations, and waiting times, matching predictions of self-organized criticality theory.
Demonstrated statistical pulse characteristics closely resembling solar flare dynamics, supporting magnetic energy dissipation and Poynting-flux-dominated jet models.
