The Extragalactic Lens VLBI Imaging Survey (ELVIS) searches for central images of lensed radio quasars, in order to measure the central density profiles of distant galaxies. Here we present sensitive multi-epoch Very Long Baseline Array (VLBA) observ

A Search for Radio Gravitational Lenses, Using the Sloan Digital Sky Survey and the Very Large Array

Autor: Boyce, Edward R., Bowman, Judd D., Bolton, Adam S., Hewitt, Jacqueline N., Burles, Scott

Publikováno v: Astrophys.J.640:62-68,2006

We report on a novel search for radio gravitational lenses. Using the Very Large Array, we imaged ten 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
