Abstract

We report the discovery and confirmation of eight new two-image lensed quasars by the Sloan Digital Sky Survey (SDSS) Quasar Lens Search. The lenses are SDSS J0904+1512 (image separation θ = 113, source redshift z _s = 1.826), SDSS J1054+2733 (θ = 127, z_s = 1.452), SDSS J1055+4628 (θ = 115, z_s = 1.249), SDSS J1131+1915 (θ = 146, z_s = 2.915), SDSS J1304+2001 (θ = 187, z_s = 2.175), SDSS J1349+1227 (θ = 300, z_s = 1.722), SDSS J1455+1447 (θ = 173, z_s = 1.424), and SDSS J1620+1203 (θ = 277, z_s = 1.158). Three of them, SDSS J1055+4628, SDSS J1455+1447, and SDSS J1620+1203, satisfy the criteria for constructing our statistical sample for studying the cosmological model. Based on galactic absorption lines of the lens galaxies, we also derive lens redshifts of z_l = 0.398 and z _l = 0.513 for SDSS J1620+1203 and the previously discovered lens SDSS J0746+4403, respectively.
