Finsler-type modification of the Coulomb law
Yakov Itin, Claus Lämmerzahl, Volker Perlick
Finsler geometry is a natural generalization of pseudo-Riemannian geometry. It can be motivated e.g. by a modified version of the Ehlers-Pirani-Schild axiomatic approach to space-t…
Motion of spinning test bodies in Kerr spacetime
Eva Hackmann, Claus Lämmerzahl, Yuri N. Obukhov +2
We investigate the motion of spinning test bodies in General Relativity. By means of a multipolar approximation method for extended test bodies we derive the equations of motion, a…
Generalized gravitomagnetic clock effect
Eva Hackmann, Claus Lämmerzahl
In General Relativity, the rotation of a gravitating body like the Earth influences the motion of orbiting test particles or satellites in a non-Newtonian way. This causes, e.g., a…
Generalized black diholes
I. Cabrera-Munguia, Claus Lämmerzahl, L. A. López +1
A 5-parametric exact solution, describing a binary system composed of identical counter-rotating black holes endowed with opposite electromagnetic charges, is constructed. The addi…
Dynamics of test particles in the general five-dimensional Myers-Perry spacetime
Valeria Diemer, Jutta Kunz, Claus Lämmerzahl +1
We present the complete set of analytical solutions of the geodesic equation in the general five-dimensional Myers-Perry spacetime in terms of the Weierstrass -, - and -…
Photon Regions and Shadows of Kerr-Newman-NUT Black Holes with a Cosmological Constant
Arne Grenzebach, Volker Perlick, Claus Lämmerzahl
We consider the Plebański class of electrovacuum solutions to the Einstein equations with a cosmological constant. These space-times, which are also known as the Kerr-Newman-NUT-(a…
