Black hole lensing in Kerr-de Sitter spacetimes
Eunice Omwoyo, Humberto Belich, Júlio C. Fabris +1
We have derived analytical solutions using Jacobi elliptic functions for bound and nearly bound photon orbits in Kerr-de Sitter (KdS) and Kerr-de Sitter Revisited (RKdS) spacetimes…

Remarks on the black hole shadows in Kerr-de Sitter space times
Eunice Omwoyo, Humberto Belich, Júlio C. Fabris +1
This work is geared towards analysis of shadows cast by Kerr-de Sitter (KdS) and Kerr-de Sitter Revisited (RKdS) black holes. Considering observers in the vicinity of the static ra…
