Abstract
Astron.J.131:1934-1941,2006 We report the discoveries of two, two-image gravitationally lensed quasars
selected from the Sloan Digital Sky Survey: SDSS J0806+2006 at z_s=1.540 and
SDSS J1353+1138 at z_s=1.629 with image separations of 1.40" and 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
z_l~0.6 in SDSS J0806+2006 and z_l~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.
