SDSS J1335+0118: A New Two-Image Gravitational Lens

arXiv:astro-ph/0311169 · doi:10.1093/pasj/56.2.399

Abstract

We report 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 the lensing galaxy. Preliminary mass modeling predicts the differential time delay Δt ~ 30 h^{-1} day assuming the redshift of the lens galaxy is 0.5.
