Influence of microlensing on the active galactic nucleus Fe Kα line

摘要

We have studied the influence of gravitational microlensing on the Fe Kα line originating from a compact accretion disc of active galactic nuclei. We found that microlensing can produce line profile deformation as well as a significant amplification of the line flux. The line deformation and line flux amplification depend not only on the parameters of the microlens but also on the disc parameters.
