UV/Optical Properties of GRBs with the Swift UVOT

The Swift Ultra-Violet/Optical Telescope has observed ~200 gamma-ray bursts (GRBs) in its first two-and-a-half years of operation. From this collection of observations we have obtained ~40 well sampled light curves. Using this dataset we present general optical/UV properties of GRBs, including filte...

Zusammenfassung:The Swift Ultra-Violet/Optical Telescope has observed ~200 gamma-ray bursts (GRBs) in its first two-and-a-half years of operation. From this collection of observations we have obtained ~40 well sampled light curves. Using this dataset we present general optical/UV properties of GRBs, including filter dependent temporal slopes and color-color relationships. We also show that correlations exist between both the 11 hour X-ray flux (0.3-10 keV) and the prompt gamma-ray fluence (15-150 keV) and the v-band magnitude at 2000 s.
