The Gravitational Microlens Influence on X-ray Spectral Line Generated by an AGN Accretion Disk
The influence of gravitational microlensing on the X-ray spectral line profiles originated from a relativistic accretion disc has been studied. Using a disc...
We have determined the gravitational torque of a sample of 45 galaxies observed at K band with the 4.2m William Herschel Telescope. The results of this sample...
