Scientific paper

Energy-time maps of Mkn 766 and NGC 3516 show hotspots traversing arcs of their orbit within the accretion disk and represent the first direct detection of the orbital motions of material around supermassive black holes. This proposal aims to make a detailed study of the hotspot orbits and lifetimes. It should also be possible to make Doppler-tomography maps for Mkn766, based on early attempts from the existing data. This spectacular new area of science, one within reach of XMM, offers amazing insight into supermassive black hole systems, yet has barely been touched upon to date. Here we show spectacular new results confirming the hotspot origin for energy-shifted Fe lines and demonstrating the urgent need for long XMM observations of Mkn 766 and NGC 3516.
