Astrophysical: Gravitational lensing

  • Publication
    Gravitational microlensing effects on the broad emission lines of quasars .
    Multiple images of QSOs are formed when the gravitational field of an intervening galaxy bends the trajectories of the light rays. The granulation of the lens...
