Multiwavelength Afterglows in Gamma‐Ray Bursts: Refreshed Shock and Jet Effects
Open accessAbstract
We present an analytical approach to calculate the hydrodynamics of the interaction between a relativistic ejecta and a surrounding medium, whose evolution serves as a model for gamma-ray burst (GRB) afterglows. We investigate the effect of the relevant model parameters on the X-ray, optical, and radio fluxes and the effect of a refreshed shock energy input and anisotropy in the ejecta on the shape of the light curves. We compare our numerical results to observed afterglows and give a quantitative description of the conditions (geometry and physical parameters) in the ejecta that are compatible with the light curves of the GRB 970508 afterglow, for which a large number of accurate flux measurements are available. We find that the radio, optical, and X-ray light curves of this afterglow can be explained satisfactorily within the spherically symmetric fireball model, assuming a delayed energy injection, or by an axially symmetric jet surrounded by a less energetic outflow.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
