Radiative properties and optical appearance of a thin accretion disk around a charged-PFDM black hole
Taiyang Zhang, Zongyuan Qin, Qian Feng +1
Accretion onto magnetically charged black holes in a perfect fluid dark matter (PFDM) background opens a new window for testing strong-field gravity. This paper investigates the ra…

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…

Detecting Black hole surrounded by perfect fluid dark matter in Kalb-Ramond fields using quasinormal modes
Zongyuan Qin, Taiyang Zhang, Qian Feng +1
This paper investigates the characteristics of quasinormal modes (QNMs) of static, spherically symmetric black holes under the combined influence of spontaneous Lorentz symmetry br…
