    Microlensing of the broad emission lines in 27 gravitationally lensed quasars. Broad line region structure and kinematics
    Aims: We aim to study the structure and kinematics of the broad line region (BLR) of a sample of 27 gravitationally lensed quasars with up to five different...

    Microlensing-based Studies of the Unresolved Structure of AGNs and the Composition of Lensing Galaxies
    Multiple images of quasars formed by gravitational lensing are typically seen through the lensing galaxy. The granulation of the galaxy in stars or other...

    Microvariability detection in quasars: An astrostatistical problem
    Microvariations probe the physics and internal structure of quasars. Unpredictability and small flux variations make this phenomenon elusive and difficult to...
