Known Gravitationally Lensed Quasars
The following is a sortable list of 204 known lensed quasars. If you find a known lens is missing, please contact firstname.lastname@example.org
The list is also available as a fits file with lens name, RA, DEC, source redshift, separation, W1 and W2 here: lensedquasars.fits
The above columns are Name, RA (J2000), DEC (J2000), b (galactic latitude), W1-W2 colour in Vega, z_qso (source redshift), sep. (maximum image separation in arcseconds), number of detected images (2 for doubles, 4 for quads), the local Gaia density per square degree based on detections within 100", number of detections for the system in Gaia DR1/DR2, and the magnitudes of those Gaia detections in DR2.
