J.-P.-U. FYNBO is an academic who published a paper in 2007 entitled The nature of the X-ray flash of August 24 2005. J.-P.-U. FYNBO published this work as part of a team: Sollerman, J.. Here is a description of this work: Aim,,. Our aim is to investigate the nature of the X-Ray Flash (XRF) of August 24, 2005. Methods. We present comprehensive photometric R-band observations of the fading optical afterglow of XRF 050824, from 11 minutes to 104 days after the burst. In addition we present observations taken during the first day in the BRIK bands and two epochs of spectroscopy. We also analyse available X-ray data. Results. The R-band lightcurve of the afterglow resembles the lightcurves of long duration Gamma-Ray Bursts (GRBs), i.E. a power-law, albeit with a rather shallow slope of α=0. 6 (Fνâˆtâˆ'α). Our late R-band images reveal the host galaxy. The rest-frame B-band luminosity is∼0. 5 L∗. The star-formation rate as determined from the [O II] emission line is∼1. 8 M⊙ yrâˆ'1. When accounting for the host contribution, the slope is α=0. 65±0. 01 and a break in the lightcurve is suggested. A potential ligh.
