Quasinormal Modes, Partial Transmission Probabilities, and Hod's Conjecture of Charged Black Holes in Perfect Fluid Dark Matter within Kalb-Ramond Gravity

Zongyuan Qin, Zheng-Wen Long

Within the Kalb-Ramond field-induced Lorentz-violating gravity, we investigate the perturbation dynamics and quasinormal mode (QNM) spectra of a charged black hole immersed in perf…

Multiscale probing of a Hernquist-type environmental black hole spacetime with the Sgr A* shadow and S2 orbital dynamics

Lai Zhao, Meirong Tang, Zheng-Wen Long +1

The supermassive black hole Sgr A* at the Galactic center provides a unique opportunity to probe the distribution of environmental matter around black holes. In this work, we adopt…

Novel topological subclass in Bardeen-AdS-class black holes

Yu-Die Wan, Peng Zhao, Zheng-Wen Long

The paper applies φ‑mapping topological current theory to the thermodynamic analysis of regular Bardeen‑AdS black holes coupled to nonlinear electrodynamics and discovers a new inn…

Gravito-Electromagnetic perturbation of higher derivative corrected Kerr-Newman black hole

Yuanyuan Ji, Zheng-Wen Long, Zheng-wen Long

We study linear gravito-electromagnetic perturbations of a slowly rotating 4-derivative corrected Kerr-Newman (KN) black hole (BH), using a perturbative approach beyond the KN geom…

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 in the framework of gravitational decoupling and investigate the geometric origin of echo-like late-tim…

Universal Thermodynamic Topological Classes of BTZ Black Holes in Einstein and F(R) Gravity

Yu-Die Wan, Peng Zhao, Meng-Yao Zhang +1

In this paper, we systematically study three classes of three-dimensional Bañados-Teitelboim-Zanelli (BTZ) black holes based on different gravitational frameworks and matter field…
