Radio, optical and infrared observations of CLASS B0128+437
A. D. Biggs, I. W. A. Browne, N. J. Jackson +4
We present new observations of the gravitational lens system CLASS B0128+437. HST observations detect a very faint, extended object in I-band with no emission from the lensed image…
MERLIN/VLA imaging of the gravitational lens system B0218+357
A. D. Biggs, I. W. A. Browne, T. W. B. Muxlow +1
Gravitational lenses offer the possibility of accurately determining the Hubble parameter (H_0) over cosmological distances, and B0218+357 is one of the most promising systems for…
VLA 8.4 GHz monitoring observations of the CLASS gravitational lens B1933+503
I. W. A. Browne, E. Xanthopoulos, A. D. Biggs +1
The complex 10-component gravitational lens B1933+503 has been monitored with the VLA during the period February to June 1998. Here we present the results of this A-configuration 8…
