Anomalous decay rate of quasinormal modes in Reissner-Nordström black holes
R. D. B. Fontana, P. A. González, Eleftherios Papantonopoulos +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…
Anomalous decay rate of quasinormal modes in Schwarzschild-dS and Schwarzschild-AdS black holes
Almendra Aragón, P. A. González, Eleftherios Papantonopoulos +1
Recently an anomalous decay rate of the quasinormal modes of a massive scalar field in Schwarzschild black holes backgrounds was reported in which the longest-lived modes are the o…
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.…
Collision of particles near a three-dimensional rotating Hořava AdS black hole
Ramón Bécar, P. A. González, Yerko Vásquez
We consider a three-dimensional rotating Hořava AdS black hole, that corresponds to a Lorentz-violating version of the BTZ black hole and we analyze the effect of the breaking of L…
Constraints on Scalar-Tensor Theory of Gravity by Solar System Tests
P. A. González, Marco Olivares, Eleftherios Papantonopoulos +1
We study the motion of particles in the background of a scalar-tensor theory of gravity in which the scalar field is kinetically coupled to Einstein tensor. We constrain the value…
Motion and trajectories of photons in a three-dimensional rotating Hořava AdS black hole
P. A. González, Marco Olivares, Eleftherios Papantonopoulos +1
We study the motion of photons in the background of a three-dimensional rotating Hořava AdS black hole that corresponds to a Lorentz-violating version of the BTZ black hole and we…
