Abstract

After nearly a decade of quiescence, the black hole X-ray transient, GRO J1655-40 became active again in 2005 February. This was perfectly timed for the new Swift satellite, which has monitored the outburst using all three instruments on board. Therefore we have obtained X-ray spectroscopy for the energy ranges 0.3-10 keV and 15-150 keV, plus optical and ultraviolet photometry (in U, B, V, UVW1, UVM2 and UVW2 filters). We use these data to study the broad-band spectral evolution of the outburst. In particular we find that comparison of the lightcurves at different bands reveals different components to the variability. Preliminary, qualitative study suggests that these component are related to the powerlaw and disc-blackbody, commonly used to model the X-ray spectra, and therefore reflect the behaviour of the jey/corona and accretion disc respectively.
