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. [ABSTRACT FROM AUTHOR] |
