Abstract

We report on the discovery of the two-image gravitationally lensed quasar SDSS J1335 + 0118. The object was selected as a lens candidate from the Sloan Digital Sky Survey. The imaging and spectroscopic follow-up observations confirm that the system exhibits two gravitationally lensed images of a quasar at z = 1.57. The image separation is 1.″56. We also detect an extended component between the two quasar images, likely to be a lensing galaxy. Preliminary mass modeling predicts a differential time delay, δt of ∼ 30h-1 day, assuming the redshift of the lens galaxy to be 0.5.
