Gravitationally lensed quasars in Gaia: III. 22 new lensed quasars from Gaia Data Release 2

Kavli Affiliate: R. G. McMahon | Summary:We report the discovery and spectroscopic confirmation of 22 new gravitationally lensed quasars found using $textitGaia$ data release 2. The selection was made using several techniques: multiple $textitGaia$ detections around objects in quasar candidate catalogues, modelling of unWISE coadd pixels using $textitGaia$ astrometry, and $textitGaia$ detections offset from photometric […]
