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…

Sagnac effect, twin paradox and space-time topology - Time and length in rotating systems and closed Minkowski space-times
Olaf Wucknitz
We discuss the Sagnac effect in standard Minkowski coordinates and with an alternative synchronization convention. We find that both approaches lead to the same result without any…

Deflection of light and particles by moving gravitational lenses
Olaf Wucknitz, Ulrich Sperhake
Various authors have investigated the problem of light deflection by radially moving gravitational lenses - with inconsistent results. In this paper we generalize the calculations…
