Quasi-normal modes of the Ayón-Beato-GarcÃa black hole surrounded by quintessence
Diego Ariel Sotelo Carrillo, Omar Pedraza, L. A. López +1
We compute the quasi-normal modes of scalar, electromagnetic, and gravitational perturbations of an Ayón-Beato-GarcÃa black hole surrounded by quintessence using the Asymptotic I…
Scattering sections from regular black holes immersed in perfect fluid dark matter
Omar Pedraza, L. A. López, Isaac Fernández
In this contribution, we investigate the scattering cross sections of black holes immersed in perfect fluid dark matter (PFDM). We present both the classical and semi-classical sca…
Quasi-normal modes and absorption section from regular black holes immersed in perfect fluid dark matter
L. O. Téllez Tovar, Omar Pedraza, L. A. López +1
We study scalar, electromagnetic and gravitational perturbations of three families of regular black holes, Hayward, Bardeen, and Ayon-Beato-GarcÃa immersed in a Perfect Fluid Dark…
Spectral analysis of Dirac materials in position-dependent magnetic and electric fields via Heun functions
Daniel O-Campa, Omar Pedraza, L. A. López +3
This work focuses on the study of the spectral problem for Dirac materials immersed in position-dependent magnetic and electric fields. To achieve this, the system of differential…
