      We present optical, near-infrared, and X-ray observations of the optical afterglow (OA) of the X-ray rich, longduration gamma-ray burst GRB 011211. Hubble Space Telescope (HST) data obtained 14, 26, 32, and 59 days after ...

    • Are short y-ray bursts collimated GRB 050709, a flare but no break 

      Watson, D.; Hjorth, J.; Jakobsson, P.; Xu, D.; Fynbo, J.; Sollerman, J.; Thone, C.C.; Pedersen, K. (2006)
      Context. From the small sample of afterglow lightcurves of short duration γ-ray bursts (GRBs), the decays are rapid, roughly following a power-law in time. It has been assumed that the afterglow emission in short GRBs is ...
