Abstract

We present one of the most intriguing results obtained with an updated catalog of 113 early time (i.e. tpk ≲ 1000 s) and 36 late time (i.e. t pk ≳ 1000 s) X-ray flares detected by Swift in the afterglows of Gamma-Ray Bursts (GRB): the evolution of the width of the flares with time. This result, together with other properties investigated on early and late time flares and bright flares, provides a clear observational property that every model aiming at explaining the GRB emission has to face.
