Abstract (from CDS):

We report the discoveries of two two-image gravitationally lensed quasars selected from the Sloan Digital Sky Survey: SDSS J0806+2006 at zs=1.540 and SDSS J1353+1138 at zs=1.629 with image separations of Δθ=1".40 and Δθ=1".41, respectively. Spectroscopic and optical/near-infrared imaging follow-up observations show that the quasar images have identical redshifts and possess extended objects between the images that are likely to be lens galaxies at zl≃0.6 in SDSS J0806+2006 and zl≃0.3 in SDSS J1353+1138. The field of SDSS J0806+2006 contains several nearby galaxies that may significantly perturb the system, and SDSS J1353+1138 has an extra component near its Einstein ring that is probably a foreground star. Simple mass models with reasonable parameters reproduce the quasar positions and fluxes of both systems.
