HVC and IVC gas in the halo of the Milky Way
Nadya Ben Bekhti, Philipp Richter, Tobias Westmeier
We combine CaII/NaI absorption and HI 21 cm emission line measurements to analyse the metal abundances, the distribution, the small-scale structure, and the physical conditions of…
A VLBI Study of the Gravitational Lens JVAS B0218+357
R. Mittal, R. Porcas, O. Wucknitz +1
We present the results of phase-referenced VLBA+Effelsberg observations at five frequencies of the gravitational lens B0218+357 to establish the precise registration of the A and B…
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…
