dc.description.abstractWe report the discovery, spectroscopic confirmation, and first lens models of the first, strongly lensed quasars from a combined search in WISE and Gaia-DR1 over the DES footprint. Their Einstein radii span a range between approximate to 2.0 arcsec and approximate to 0.4 arcsec. Two of these (WGD2038-4008, RA = 20: 38: 02.65, Dec. = -40: 08: 14.64; WGD2021-4115, RA = 20: 21: 39.45, Dec. = -41:15:57.11) also have confirmed deflector redshifts. The four-image lens WGD2038-4008, with source and deflector redshifts s = 0.777 +/- 0.001 and z(l) = 0.230 +/- 0.002, respectively, has a deflector with radius R-eff approximate to 3.4 arcsec, stellar mass log(M-star /M-circle dot) = 11.64(-0.43)(+ 0.20), and extended isophotal shape variation. Simple lens models yield Einstein radii R-E = (1.30 +/- 0.04) arcsec, axis ratio q = 0.75 +/- 0.1 (compatible with that of the starlight) and considerable shear-ellipticity degeneracies. The two-image lens WGD2021-4115 has z(s) = 1.390 +/- 0.001 and z(l) = 0.335 +/- 0.002, and Einstein radius R-E = (1.1 +/- 0.1) arcsec, but higher-resolution imaging is needed to accurately separate the deflector and faint quasar image. Analogous lens model degeneracies hold for the other six lenses (J0146-1133, J0150-4041, J0235-2433, J0245-0556, J0259-2338, and J0508-2748) shown in this paper.pt_BR
