Keck Spectroscopy of Three Gravitational Lens Systems Discovered in the JVAS and CLASS Surveys
C. D. Fassnacht, J. G. Cohen
We present spectra of three gravitational lens systems taken with the Low Resolution Imaging Spectrograph on the W. M. Keck Telescopes. All of the systems were discovered in the JV…
The complex gravitational lens system B1933+503
C. M. Sykes, I. W. A. Browne, N. J. Jackson +15
We report the discovery of the most complex arcsec-scale radio gravitational lens system yet known. B1933+503 was found during the course of the CLASS survey and MERLIN and VLA rad…
A complete infrared Einstein ring in the gravitational lens system B1938+666
L. J. King, N. J. Jackson, R. D. Blandford +8
We report the discovery, using NICMOS on the Hubble Space Telescope, of an arcsecond-diameter Einstein ring in the gravitational lens system B1938+666. The lensing galaxy is also d…
