High resolution observations and mass modelling of the CLASS gravitational lens B1152+199
D. Rusin, M. Norbury, A. D. Biggs +5
We present a series of high resolution radio and optical observations of the CLASS gravitational lens system B1152+199 obtained with the Multi-Element Radio-Linked Interferometer N…
CLASS B1152+199 and B1359+154: Two New Gravitational Lens Systems Discovered in the Cosmic Lens All-Sky Survey
S. T. Myers, D. Rusin, C. D. Fassnacht +9
The third phase of the Cosmic Lens All-Sky Survey (CLASS) has recently been completed, bringing the total number of sources imaged to over 15000 in the CLASS and JVAS combined surv…
Measuring Cosmological Parameters with the JVAS and CLASS Gravitational Lens Surveys
P. Helbig, R. D. Blandford, I. W. A. Browne +11
The JVAS (Jodrell Bank-VLA Astrometric Survey) and CLASS (Cosmic Lens All-Sky Survey) are well-defined surveys containing about ten thousand flat-spectrum radio sources. For many r…
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…
