    OGLE-2018-BLG-0799Lb: a q 2.7 × 10<SUP>-3</SUP> planet with Spitzer parallax
    We report the discovery and analysis of a planet in the microlensing event OGLE-2018-BLG-0799. The planetary signal was observed by several ground-based...

    Peculiar Transverse Velocities of Galaxies from Quasar Microlensing. Tentative Estimate of the Peculiar Velocity Dispersion at z ~ 0.5
    We propose to use the flux variability of lensed quasar images induced by gravitational microlensing to measure the transverse peculiar velocity of lens...

    Photometric Variability of the Gravitational Lens 0142-100 (UM 673)
    We present the results of a photometric CCD monitoring of the gravitational lens system UM 673 that took place from 1995 to 2000. In total, the doubly imaged...

    Planck 2013 results. XVII. Gravitational lensing by large-scale structure
    On the arcminute angular scales probed by Planck, the cosmic microwave background (CMB) anisotropies are gently perturbed by gravitational lensing. Here we...
