The absorption properties of gamma-ray burst afterglows measured by BeppoSAX
Alan Owens, M. Guainazzi, T. Oosterbroek +14
We present an analysis of the X-ray absorption properties of 6 gamma-ray burst (GRB) afterglows measured with BeppoSAX. Between 8 hrs and 20 hrs after the initial GRB trigger, indi…
