Stability and thermodynamics of brane black holes
E. Abdalla, B. Cuadros-Melgar, A. B. Pavan +1
We consider scalar and axial gravitational perturbations of black hole solutions in brane world scenarios. We show that perturbation dynamics is surprisingly similar to the Schwarz…
Field propagation in de Sitter black holes
C. Molina, D. Giugno, E. Abdalla +1
We present an exhaustive analysis of scalar, electromagnetic and gravitational perturbations in the background of Schwarzchild-de Sitter and Reissner-Nordstrom-de Sitter spacetimes…
Area Quantization in Quasi-Extreme Black Holes
E. Abdalla, K. H. C. Castello-Branco, A. Lima-Santos
We consider quasi-extreme Kerr and quasi-extreme Schwarzschild-de Sitter black holes. From the known analytical expressions obtained for their quasi-normal modes frequencies, we su…
