Study of errors in strong gravitational lensing
Thomas P. Kling, Simonetta Frittelli
We examine the accuracy of strong gravitational lensing determinations of the mass of galaxy clusters by comparing the conventional approach with the numerical integration of the f…

Aberration by gravitational lenses in motion
Simonetta Frittelli
It is known that a fully relativistic integration of the null geodesics of a weak perturbation of flat spacetime leads to a correction of order to the bending angle and time…

On bending angles by gravitational lenses in motion
Simonetta Frittelli
The bending of lightrays by the gravitational field of a ``lens'' that is moving relative to the observer is calculated within the approximation of weak fields, small angles and th…
