Tomographic modelling of H 1743-322

Results of fitting a tomographic model to the ~4s quasi periodic oscillation (QPO) in XMM-Newton and NuSTAR data from the black hole X-ray binary system H 1743-322. This is an animated version of Fig 3 in Ingram et al (2016). The most intensely illuminated patches of the disc rotate about the disc surface, causing the iron line to rock from red to blue shifted during a QPO cycle.
