Motion Statistics in the CJ Survey -- The Status in October 2002
R. C. Vermeulen, S. Britzen, G. B. Taylor +4
In the Caltech-Jodrell Survey of bright flat-spectrum radio sources, 3-5 epochs have now been observed for nearly all 293 sources; a uniquely large sample. The derivation of compon…
B0850+054: a new gravitational lens system from CLASS
A. D. Biggs, D. Rusin, I. W. A. Browne +12
We report the discovery of a new gravitational lens system from the CLASS survey. Radio observations with the VLA, the WSRT and MERLIN show that the radio source B0850+054 is compr…
Global 8.4-GHz VLBI observations of JVAS B0218+357
A. D. Biggs, O. Wucknitz, R. W. Porcas +4
In this paper we present new observations of the gravitational lens system JVAS B0218+357 made with a global VLBI network at a frequency of 8.4 GHz. Our maps have an rms noise of 3…
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…
