Iron line Doppler tomography with quasi-periodic oscillations

We propose three joint XMMNewton and NuSTAR observations of the black holebinary H 1743322, each covering a single XMMNewton orbit and 70ks of NuSTARtime, sampling different stages of spectral evolution during the rise tooutburst. This builds upon our recent discovery that the iron line centroidenergy in this source varies systematically over the course of a 4s QPO cycle,providing strong evidence that the QPO is driven by relativistic precession. Wenow aim to sample the same source when displaying a range of higher QPOfrequencies to explore the evolution of the iron line profile phase dependencewith QPO frequency and compare with the prediction of relativistic precession.We will trigger the observations from Swift monitoring throughout the outburst. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
