Moving Corona and the Line Profile of the Relativistic Broad Iron Emission Line

Abstract Iron fluorescence emission lines from X-ray binaries and active galactic nuclei are important diagnostic tools for studying the physical processes near event horizon of both stellar-mass black holes in supermassive nuclei. In this work, we investigate line profile relativistic broad iron cool accretion disk a hole due to asymmetric illumination moving corona, which moves away with velocity. Both off-axis location radial velocity corona considered. Our results clearly show that dependent on position since region below receives more flux, is most factor affecting profiles. As expected, if close receding part rotating disk, red peak enhanced, while blue weakened profile, central energy low. Conversely, approaching strong high, even higher than intrinsic line. Due beaming effect high illuminates outer leads disappearing there being only one
