Abstract

We report on a novel search for radio gravitational lenses. Using the Very Large Array, we imaged 10 candidates with both dual redshifts in Sloan Digital Sky Survey spectra and 1.4 GHz radio flux ≥2 mJy in the FIRST survey. The VLA maps show that in each case the radio emission is associated with the foreground galaxy rather than being lensed emission from the background galaxy, although at least four of our targets are strong lenses at optical wavelengths. These SDSS dual-redshift systems do not have lensed radio emission at the sensitivity of current radio surveys.
