Eight New Quasar Lenses from the Sloan Digital Sky Survey Quasar Lens Search
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 SDSSJ0904+1512 (image separation θ=1"13, source redshift zs=1.826), SDSSJ1054+2733 (θ=1"27, zs=1.452), SDSSJ1055+4628 (θ=1"15, zs=1.249), SDSSJ1131+1915 (θ=1"46, zs=2.915), SDSSJ1304+2001 (θ=1"87, zs=2.175), SDSSJ1349+1227 (θ=3"00, zs=1.722), SDSSJ1455+1447 (θ=1"73, zs=1.424), and SDSSJ1620+1203 (θ=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.
