GRBs. Our model slightly over predicts the radio fluxes, indicating that a more complicated modelling might be required in some cases. These findings provide crucial constraints on VHE GRB emission sites and mechanisms (Abridged). [8/8 of https://arxiv.…
that VHE GRBs tend to occur in environments with lower magnetic fields and higher ambient medium densities. Interestingly, VHE GRBs lie at the edge of the 3-$\sigma$ region of the $E_{\rm k,iso}$ - $\epsilon_B$ correlation observed in other energetic [7…
emission mechanism, with negligible contribution from EC. Most VHE GRBs are well described by the forward shock model in a spherical jet configuration, where constant density interstellar medium is preferred over wind medium. Additionally, we find [6/8 …
extragalactic background light correction, and the Markov chain Monte Carlo techniques. Our analysis constrains key parameters governing the emission and surrounding environments of these GRBs. The results indicate that SSC is the dominant VHE [5/8 of h…
