We report the discovery , spectroscopic confirmation and first lens models of the first two , strongly lensed quasars from a combined search in WISE and Gaia over the DES footprint .
The four-image lens WGD2038-4008 ( r.a.=20:38:02.65 , dec.=-40:08:14.64 ) has source- and lens-redshifts z _ { s } = 0.777 \pm 0.001 and z _ { l } = 0.230 \pm 0.002 respectively .
Its deflector has effective radius R _ { eff } \approx 3.4 ^ { \prime \prime } , stellar mass \log ( M _ { \star } / M _ { \odot } ) = 11.64 ^ { +0.20 } _ { -0.43 } , and shows extended isophotal shape variation .
Simple lens models yield Einstein radii R _ { E } = ( 1.30 \pm 0.04 ) ^ { \prime \prime } , axis ratio q = 0.75 \pm 0.1 ( compatible with that of the starlight ) and considerable shear-ellipticity degeneracies .
The two-image lens WGD2021-4115 ( r.a.=20:21:39.45 , dec.=–41:15:57.11 ) has z _ { s } = 1.390 \pm 0.001 and z _ { l } = 0.335 \pm 0.002 , and Einstein radius R _ { E } = ( 1.1 \pm 0.1 ) ^ { \prime \prime } , but higher-resolution imaging is needed to accurately separate the deflector and faint quasar image .
We also show high-rank candidate doubles selected this way , some of which have been independently identified with different techniques , and discuss a DES+WISE quasar multiplet selection .
