Galactic-scale Quasar Pairs from the Sloan Digital Sky Survey and Gaia DR3
We perform a systematic search for galactic-scale quasar pairs and small-scale (<3″) lenses using the Sloan Digital Sky Survey (SDSS) DR16 quasar catalog and Gaia DR3, and identify 136 double quasar candidates from 1120 Gaia-resolved pairs after a magnitude and redshift cut of G < 20.5 and z > 0.5...
