X-ray flare in XRF 050406: evidence for prolonged engine activity
We present observations of XRF 050406, the first burst detected by Swift showing a flare in its X-ray light curve. During this flare, which peaks at s after the BAT trigger, a flux variation of in a very short time was observed. Its measured fluence in the 0.2-10 keV band …
