Polar quasinormal modes of the scalarized Einstein-Gauss-Bonnet black holes
Jose Luis Blázquez-Salcedo, Daniela D. Doneva, Sarah Kahlen +3
We study the polar quasinormal modes of spontaneously scalarized black holes in Einstein-Gauss-Bonnet theory. In previous works we showed that a set of nodeless solutions of the fu…
Observational signatures of strongly naked singularities: image of the thin accretion disk
Galin Gyulchev, Jutta Kunz, Petya Nedkova +2
We study the optical appearance of a thin accretion disk around the strongly naked static Janis-Newman-Winicour singularity. The solution does not possess a photon sphere, which re…
Axial perturbations of the scalarized Einstein-Gauss-Bonnet black holes
Jose Luis Blázquez-Salcedo, Daniela D. Doneva, Sarah Kahlen +3
We study the axial perturbations of spontaneously scalarized black holes in Einstein-Gauss-Bonnet (EGB) theories. We consider the nodeless solutions of the fundamental branch of th…
Quasi-periodic oscillations from the accretion disk around distorted black holes
Efthimia Deligianni, Jutta Kunz, Petya Nedkova
We study the quasi-periodic oscillations from the accretion disk around the distorted Schwarzschild black hole in the framework of the resonant models. We confine ourselves to the…
