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
${1\rlap {.}{}^{\mathrm {\prime \prime }}56}$
. 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,
$\Delta t$
of
$\sim30 \, h^{-1} \mathrm{day}$
, assuming the redshift of the lens galaxy to be
$0.5$
.
