Light escape cones in local reference frames of Kerr-de Sitter black hole spacetimes and related black hole shadows
Zdeněk Stuchlík, Daniel Charbulák, Jan Schee
We construct the light escape cones of isotropic spot sources of radiation residing in special classes of reference frames in the Kerr-de Sitter (KdS) black hole spacetimes, namely…

Electromagnetic perturbations of black holes in general relativity coupled to nonlinear electrodynamics
Bobir Toshmatov, Zdeněk Stuchlík, Jan Schee +1
The electromagnetic (EM) perturbations of the black hole solutions in general relativity coupled to nonlinear electrodynamics (NED) are studied for both electrically and magnetical…
