Decoding disc-corona-jet variability in hard state black hole X-ray binaries
Abstract
We request 4 additional TOO EPIC-pn observations of the hard states of BHXRBs, to expand our highly successful campaign of triggering based on significant changes in characteristic timing signatures with respect to those seen in earlier hard state observations. Our campaign has already proven that an unstable disc drives the variability seen in hard states up to 1 Hz, and that the iron line becomes narrower as Lorentzian frequencies decrease. We will increase our coverage of the factor 100 variation in Lorentzian frequencies throughout the hard state, to more smoothly map the evolution of disc and power-law variability and the relationship to disc structure. We will use simultaneous fast optical timing from the ground, to measure the direct connection between disc and jet.
