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

These results provide support for RMSs as potential candidates for the prompt emission in GRBs.

C2weakest assumption

The results are reported for one specific internal-collision setup (including the assumed redshift z=1 and the chosen shell parameters); the spectral features and efficiency may change substantially for other collision geometries or Lorentz factors.

C3one line summary

Simulations of radiation-mediated shocks below the photosphere in a GRB jet produce a ~0.1 s pulse with 23% radiative efficiency, a spectrum that settles into a curved low-energy shape plus a high-energy power law cutting off at ~5 MeV, and evolving indices that support RMS as a prompt-emission site
