Intrinsic intraday variability in the gravitational lens system B0218+357
A. D. Biggs, I. W. A. Browne, P. N. Wilkinson
Radio monitoring of the gravitational lens system B0218+357 reveals it to be a highly variable source with variations on timescales of a few days correlated in both images. This sh…
VLA and MERLIN monitoring observations of the gravitational lens system B1030+074
E. Xanthopoulos, I. W. A. Browne, A. R. Patnaik +1
We present VLA and MERLIN monitoring data of the JVAS gravitational lens system B1030+074. The system was monitored with the VLA from February 1998 to October 1998 at 8.4-GHz durin…
The JVAS/CLASS 6'' to 15'' Lens Search
P. M. Phillips, I. W. A. Browne, P. N. Wilkinson +1
We present the strategy and status of a gravitational lens search for multiple imaging with angular separations between 6'' and 15'' with the combined JVAS and CLASS data set of ~1…
The core-jet structure of the JVAS gravitational lens B1030+074
E. Xanthopoulos, M. Norbury, A. Karidis +6
We present results from VLBA+Effelsberg 1.7 GHz, VLBA 8.4 GHz and VLBA 15 GHz observations of the JVAS gravitational lens system B1030+074. The VLBA+Effelsberg 1.7 GHz data with 3…
CLASS B0827+525: `Dark lens' or binary radio-loud quasar?
L. V. E. Koopmans, A. G. de Bruyn, C. D. Fassnacht +12
We present radio, optical, near-infrared and spectroscopic observations of the source B0827+525. We consider this source as the best candidate from the Cosmic Lens All-Sky Survey (…
