Achromatic Breaks for Swift GRBs: Any Evidence?
arXiv:astro-ph/0612643 · doi:10.1393/ncb/i2007-10239-4
Abstract
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.
