We report the results of the Swift andXMM-Newtonobservations of the Swift -discoveredGRB060729 (T90 1⁄4 115 s). The afterglow of this burst was exceptionally bright in X-rays as well as at UV/optical wavelengths, showing an unusually long slow decay phase ( 1⁄4 0:14 0:02), suggesting a larger energy injection phase at early times than in other bursts. The X… CONTINUE READING
