Nearly Identical Quasar Pairs

The following is a sortable list of 24 known small separation quasar pairs. They represent a population for which a lensing galaxy has not yet been identified, either through lack of data, or they are actually binary quasars. If you find a known NIQ that is missing, please contact clemon@ast.cam.ac.uk

The list is also available as a fits file with lens name, RA, DEC, source redshift and separation here: NIQs.fits
