摘要: The Swift era has posed a challenge to the standard blast-wave model of gamma-ray burst (GRB) afterglows. key observational features expected within are rarely observed, such as achromatic steepening (‘jet break’) light curves. observed afterglow curves showcase additional complex requiring modifications model. Here we present optical/near-infrared observations, millimetre upper limits and comprehensive broad-band modelling bright GRB 0505025A, detected by Swift. This cannot be explained simplistic form We attempt multiwavelength using (i) forward–reverse shock model, (ii) two-component outflow (iii) with wind termination shock. explain evolution afterglow. is able average behaviour very well but reproduce fluctuations in early X-ray curve. reproduces deviates from global late-time
