Near-horizon Geodesic Instabilities and Anomalous Decay of Quasinormal Modes in Weyl Black Holes
Gerasimos Kouniatalis, P. A. González, Eleftherios Papantonopoulos +1
We study the stability of the Weyl geometry considering an exact black hole solution. By calculating the geodesics of massless and massive scalar fields orbiting outside the Weyl b…
Massive Particle Motion Around Horndeski Black Holes
D. A. Carvajal, P. A. González, Marco Olivares +2
The time-like structure of the four-dimensional asymptotically flat Horndeski black holes is studied in detail. Focusing on the motion of massive neutral test particles, we constru…
Massive scalar field perturbations of 4D de Sitter Einstein-Gauss-Bonnet black holes
Ramón Bécar, P. A. González, Eleftherios Papantonopoulos +1
We investigate the propagation of massive scalar fields in the background of four-dimensional Einstein-Gauss-Bonnet black holes with de Sitter (dS) asymptotics. Our study focuses o…
Study of Null Geodesics and their Stability in Horndeski Black Holes
D. A. Carvajal, P. A. González, Marco Olivares +2
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 the Einstein tensor and we present the n…
