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…

Degeneracies and scaling relations in general power-law models for gravitational lenses
Olaf Wucknitz
The time delay in gravitational lenses can be used to derive the Hubble constant in a relatively simple way. The results of this method are less dependent on astrophysical assumpti…
