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 of the Ayón-Beato-García 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-García black hole surrounded by quintessence using the Asymptotic Ite…
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-García immersed in a Perfect Fluid Dark…
Quasinormal modes of the Schwarzschild black hole with a deficit solid angle and quintessence-like matter: Improved asymptotic iteration method
L. A. López, Omar Pedraza, Roberto Arceo +1
We study the quasinormal modes (QNM) for scalar, and electromagnetic perturbations in the Schwarzschild black hole with a deficit solid angle and quintessence-like matter. Using th…
