Optical Appearance and Ringdown of Black Holes in a Kalb Ramond Field Coupled to Perfect Fluid Dark Matter
Qi-Qi Liang, Zi-Qiang Cai, Dong Liu +1
This paper investigates the optical and dynamical properties of a static spherically symmetric black hole in the presence of a Kalb--Ramond (KR) field coupled to perfect fluid dark…
Echoes of a hairy black hole from gravitational decoupling
Yi Yang, Ali Ovgun, Gaetano Lambiase +2
We study axial gravitational perturbations of a hairy black hole constructed within the framework of gravitational decoupling and investigate the geometric origin of echo-like late…
Observational properties and quasinormal Modes of the Hayward black Hole surrounded by a cloud of strings
Qi-Qi Liang, Ziqiang Cai, Dong Liu +1
In this work, we explored the Hayward black hole surrounded by a cloud of strings, with a focus on the effects of the regularization parameter and the string cloud parameter $a…
Ringdown of a black hole sourced by a Burkert-density effective anisotropic source
Yi Yang, Gaetano Lambiase, Ali Ovgun +2
We construct a static, spherically symmetric black hole spacetime sourced by an effective anisotropic matter distribution whose energy density follows the cored Burkert profile. Th…
Quasinormal Modes of Schwarzschild Black Holes in the Dehnen-(1, 4, 5/2) Type Dark Matter Halos
Qi-Qi Liang, Dong Liu, Zheng-Wen Long
The Dehnen - type dark matter density distribution model is mainly used for dwarf galaxies. In recent years, researchers have speculated that black holes may exist in this dark mat…
Quasinormal Modes and Greybody Factors of Scalar Field Perturbations in the NED Corrected Charged Black Hole Spacetime
Jie Liang, Dong Liu, Zheng-Wen Long
Inspired by the quark-antiquark confinement potential, Mazharimousavi et al. \cite{Mazharimousavi:2023okd} proposed a nonlinear electrodynamics (NED) model, and based on this model…
