Instabilities in Kerr spacetimes
(World Scientific, 2011-12)
We present a generalization of previous results regarding the stability under gravitational perturbations of nakedly singular super extreme Kerr spacetime and Kerr black hole interior beyond the Cauchy horizon. To do so ...
Gravitational energy of Kerr and Kerr anti-de Sitter space-times in the teleparallel geometry
(2003-11-01)
In the context of the hamiltonian formulation of the teleparallel equivalent of general relativity we compute the gravitational energy of Kerr and Kerr Anti-de Sitter (Kerr-AdS) space-times. The present calculation is ...

In the context of the hamiltonian formulation of the teleparallel equivalent of general relativity we compute the gravitational energy of Kerr and Kerr Anti-de Sitter (Kerr-AdS) space-times. The present calculation is ...
Massive vector fields in Kerr-Newman and Kerr-Sen black hole spacetimes
(2020-04-01)
The superradiant instability modes of ultralight massive vector bosons are studied for weakly charged rotating black holes in Einstein-Maxwell gravity (the Kerr- Newman solution) and low-energy heterotic string theory (the ...
Axial-vector torsion and the teleparallel Kerr spacetime
(Iop Publishing Ltd, 2001-03-07)
In the context of the teleparallel equivalent of general relativity, we obtain the tetrad and the torsion fields of the stationary axisymmetric Kerr spacetime. It is shown that, in the slow rotation and weak-field ...
