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…

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.…
