HI kinematics in a massive spiral galaxy at z=0.89
L. V. E. Koopmans, A. G. de Bruyn
We present a kinematic model of the neutral-hydrogen in the spiral galaxy of the lens system PKS1830-211, based on a Multi Element Radio-Linked Interferometer (MERLIN) 1.4-GHz radi…

Extrinsic Radio Variability of JVAS/CLASS Gravitational Lenses
L. V. E. Koopmans, A. Biggs, R. D. Blandford +6
We present flux-ratio curves of the fold and cusp (i.e. close multiple) images of six JVAS/CLASS gravitational lens systems. The data were obtained over a period of 8.5 months in 2…
