Discovery of three strongly lensed quasars in the Sloan Digital Sky Survey

Understand

We present the discovery of 3 quasar lenses in the Sloan Digital Sky Survey (SDSS), selected using two novel photometry-based selection techniques.

• The J0941+0518 system, with two point sources separated by 5.46" on either side of a galaxy, has source and lens redshifts $z_s = 1.54$ and $z_l = 0.343$.
• The AO-assisted images of J2211+1929 show two point sources separated by 1.04", corresponding to the same quasar at $z_s = 1.07,$ besides the lens galaxy and Einstein ring.
• Images of J2257+2349 show two point sources separated by 1.67" on either side of an E/S0 galaxy.
