Quasinormal modes of the Hayward black hole surrounded by quintessence: scalar, electromagnetic and gravitational perturbations
Omar Pedraza, L. A. López, R. Arceo +1
We study the quasi-normal modes for scalar, electromagnetic, and gravitational axial perturbations in the Hayward regular black hole surrounded by quintessence (HBH-). Using t…
Scattering and absorption sections of Schwarzschild-anti de Sitter with quintessence
Valeria Ramírez, L. A. López, Omar Pedraza +1
In this paper, we study the scattering and absorption sections of the Schwarzschild--anti de Sitter black hole surrounded by quintessence. The critical values of the cosmological c…
Birefringence and QuasiNormal Modes of the Einstein-Euler-Heisenberg Black Hole
Nora Bretón, L. A. López
In this contribution we study the birefringence and the quasinormal modes (QNM) in the eikonal approximation, of the Einstein-Euler-Heisenberg black hole (EEH-BH) . The EEH-BH is a…
Redshift of light emitted by particles orbiting a black hole immersed in a strong magnetic field
L. A. López, Nora Bretón
In this paper we analyze the frequency shifts of the light emitted by particles describing stable circular geodesics around a static black hole immersed in an external magnetic fie…
Effects of quintessence on scattering and absorption sections of black holes
L. A. López, Omar Pedraza
Basing on the ideas used by Kiselev, we study three black holes surrounded by quintessence and the effects of quintessence on the classical and semiclassical scattering cross-secti…
