The Redshift of the Lensed Object in the Einstein Ring B0218+357
Abstract
We present a secure redshift of z=0.944+/-0.002 for the lensed object in the Einstein ring gravitational lens B0218+357 based on five broad emission lines, in good agreement with our preliminary value announced several years ago based solely on the detection of a single emission line.
Based on observations obtained at the W.M. Keck Observatory, which is operated jointly by the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration.- Publication:
