Radio Microlensing: Past, Present & Near Future
L. V. E. Koopmans, A. G. de Bruyn, C. D. Fassnacht +3
Strongly correlated non-intrinsic variability between 5 and 8.5 GHz has been observed in one of the lensed images of the gravitational lens B1600+434. These non-intrinsic (i.e. `ex…

A radio-microlensing caustic crossing in B1600+434?
L. V. E. Koopmans, A. G. de Bruyn, J. Wambsganss +1
First, we review the current status of the detection of strong `external' variability in the CLASS gravitational B1600+434, focusing on the 1998 VLA 8.5-GHz and 1998/9 WSRT multi-f…
