Quasinormal modes of nonlinear electromagnetic black holes from unstable null geodesics
N. Breton, L. A. Lopez
The expressions for the quasinormal modes (QNMs) of black holes with nonlinear electrodynamics, calculated in the eikonal approximation, are presented. In the eikonal limit QNMs of…

Probing bulk viscous matter-dominated models with Gamma-ray bursts
A. Montiel, N. Bretón
In this paper we extend the range of consistency of a constant bulk viscosity model to redshifts up to . In this model the dark sector of the cosmic substratum is a visc…

5D gravitational waves from complexified black rings
N. Bretón, A. Feinstein, L. A. López
In this paper we construct and briefly study the 5D time-dependent solutions of general relativity obtained via double analytic continuation of the black hole (Myers-Perry) and of…
