Extreme Dilaton Black Holes in 2 +1 Dimensions: Quasinormal modes
Sharmanthie Fernando, P. A. González, Yerko Vásquez
We study neutral massless scalar field perturbations around an extreme dilaton black hole in 2 +1 dimensions: the wave equations of the massless scalar field is shown to be exactly…
Quasinormal modes for massive charged scalar fields in Reissner-Nordström dS black holes: anomalous decay rate
P. A. González, Eleftherios Papantonopoulos, Joel Saavedra +1
The anomalous decay rate of the quasinormal modes occurs when the longest-lived modes are the ones with higher angular number. Such behaviour has been recently studied in different…
Null geodesics in five-dimensional Reissner-Nordström anti-de Sitter black hole
P. A. González, Marco Olivares, Yerko Vásquez +1
The study of the motion of photons around massive bodies is one of the most useful tools to know the geodesic structure associated with said gravitational source. In the present wo…
Massive Dirac quasinormal modes in Schwarzschild-dS black holes: anomalous decay rate and fine structure
Almendra Aragón, Ramón Bécar, P. A. González +1
Recently, the anomalous decay rate of quasinormal modes has been studied for some geometries under scalar field perturbations, which occurs when the longest-lived modes are the one…
Quasinormal modes and their anomalous behavior for black holes in gravity
Almendra Aragón, P. A. González, Eleftherios Papantonopoulos +1
We study the propagation of scalar fields in the background of an asymptotically de-Sitter black hole solution in gravity. The aim of this work is to analyze in modified the…
Perturbative and nonperturbative quasinormal modes of 4D Einstein-Gauss-Bonnet black holes
Almendra Aragón, Ramón Bécar, P. A. González +1
We study the propagation of probe scalar fields in the background of 4D Einstein-Gauss-Bonnet black holes with anti-de Sitter (AdS) asymptotics and calculate the quasinormal modes.…
