标题： Achromatic Breaks for Swift GRBs: Any Evidence?

摘要： 与预期相反，在Swift时代的伽马射线暴余辉的多波段高质量数据可用性，并没有使我们能够完全确认标准余辉图景中最基本的特征之一：衰减光变曲线中存在无色变断裂。 我们简要回顾了迄今为止确定的最有趣的案例。 显示英文摘要

摘要： The availability of multi-wavelength high-quality data of gamma-ray burst afterglows in the Swift era, contrary to the expectations, did not allow us to fully confirm yet one of the most fundamental features of the standard afterglow picture: the presence of an achromatic break in the decaying light curve. We briefly review the most interesting cases identified so far.
