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…

Non-linear numerical Schemes in General Relativity
Ulrich Sperhake
This thesis describes the application of numerical techniques to solve Einstein's field equations in three distinct cases. First we present the first long-term stable second order…

Non-linear radial oscillations of neutron stars: Mode-coupling results
Uli Sperhake, Philippos Papadopoulos, Nils Andersson
The non-linear behaviour of oscillation modes in compact stars is a topic of considerable current interest. Accurate numerical studies of such phenomena are likely to require power…
