Analytic solutions of the geodesic equation in axially symmetric space-times
TL;DR: The complete sets of analytic solutions of the geodesic equation in Taub-NUT-(anti-) de Sitter, Kerr-anti-)de Sitter and also in general Plebanski-Demianski space-times without acceleration are presented in this article.

Geodesic equations in black hole space-times with cosmological constant
Eva Hackmann
- 01 Jan 2010
TL;DR: In particular, exact analytic treatments can finally answer the question whether the cosmological expansion, modeled here by a cosmology constant, has an observable influence on effects such as the Pioneer anomaly or the creation of gravitational waves as mentioned in this paper.

Michal Zajaček,Arman Tursunov,Andreas Eckart,Silke Britzen,Eva Hackmann,Vladimir Karas,Zdeněk Stuchlík,Bozena Czerny,J. Anton Zensus +8 more
TL;DR: In this paper, the authors summarize the results concerning the observational constraints on the electric charge associated with the Galactic centre black hole -Sgr A*, according to the no-hair theorem, every astrophysical black hole, including supermassive black holes, is characterized by at most three classical, externally observable parameters -mass, spin, and electric charge.
