Evidence for chromatic X-ray light-curve breaks in Swift GRB afterglows and their theoretical implications
The power-law decay of the X-ray emission of GRB afterglows 050319, 050401, 050607, 050713A, 050802 and 050922C exhibits a steepening at about 1–4 hours after the burst which, surprisingly, is not accompanied by a break in the optical emission. If it is assumed that both the optical and X-ray afterglows arise from the same outflow then, in the framework of the standard forward shock model, the ...
متن کاملOptical and X-Ray Observations of GRB 060526: A Complex Afterglow with An Achromatic Jet Break
We obtained 98 R-band and 18 B, r, i images of the optical afterglow of GRB 060526 (z = 3.21) with the MDM 1.3m, 2.4m, and the PROMPT telescopes in Cerro Tololo over the 5 nights following the burst trigger. Combining these data with other optical observations reported in GCN and the Swift-XRT observations, we compare the optical and X-ray afterglow light curves of GRB 060526. Both the optical ...

15 صفحه اولJet-breaks in the X-ray Light-Curves of Swift GRB Afterglows
In the set of 236 GRB afterglows observed by Swift between January 2005 and March 2007, we identify 30 X-ray light-curves whose power-law fall-off exhibit a steepening (”break”) at 0.1–10 day after trigger, to a decay steeper than t−1.5. For most of these afterglows, the X-ray spectral slope and the decay indices before and after the break can be accommodated by the standard jet model although ...
