We propose three joint XMM-Newton and NuSTAR observations of the black holebinary H 1743-322, each covering a single XMM-Newton 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.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
