The gravitational microlens influence on X-ray spectral line generated by an AGN accretion disc

The gravitational microlens influence on X-ray spectral line generated by an AGN accretion disc

The influence of gravitational microlensing on the X-ray spectral line profiles originated from a relativistic accretion disc has been studied. Using a disc model, we show that microlensing can induce noticeable changes in the line shapes when the Einstein ring radius associated with the microlens i...
