First Direct Evidence for Keplerian Rotation in Quasar Inner Broad Line Regions
C. Fian, J. Jiménez-Vicente, E. Mediavilla +4
We introduce a novel method to derive rotation curves with light-day spatial resolution of the inner regions of lensed quasars. We aim to probe the kinematics of the inner part of…
