Reverse Shock Emission in Gamma-Ray Bursts Revisited

الملخص EN

A generic synchrotron external shock model is the widely preferred paradigm used to interpret the broadband afterglow data of gamma-ray bursts (GRBs), including predicted observable signatures from areverse shock which have been confirmed by observations.

Investigations of the nature of the reverse shock emission can provide valuable insights into the intrinsic properties of the GRB ejecta.

Here we briefly review the standard and the extended models of the reverse shock emission, discussing the connection between the theory and observations, including the implications of the latest observational advances.
