Eight New Quasar Lenses From the Sloan Digital Sky Survey Quasar Lens Search

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 SDSSJ0904+1512 (image separation =1"13, source redshift zₛ=1. 826), SDSSJ1054+2733 (=1"27, zₛ=1. 452), SDSSJ1055+4628 (=1"15, zₛ=1. 249), SDSSJ1131+1915 (=1"46, zₛ=2. 915), SDSSJ1304+2001 (=1"87, zₛ=2. 175), SDSSJ1349+1227 (=3"00, zₛ=1. 722), SDSSJ1455+1447 (=1"73, zₛ=1. 424), and SDSSJ1620+1203 (=2"77, zₛ=1. 158). Three of them, SDSSJ1055+4628, SDSSJ1455+1447, and SDSSJ1620+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 zₗ=0. 398 and zₗ=0. 513 for SDSSJ1620+1203 and the previously discovered lens SDSSJ0746+4403, respectively.
