Black holes immersed in modified Chaplygin-like dark fluid and cloud of strings: shadows, quasinomal modes and greybody factors
Hao-Peng Yan, Zeng-Yi Zhang, Xiao-Jun Yue +1
We present a unified investigation of black hole shadows, quasinormal modes (QNMs), and greybody factors (GBFs) for a static, spherically symmetric black hole within a composite en…

Black holes immersed in modified Chaplygin-like dark fluid and cloud of strings: geodesics, shadows, and images
Xiang-Qian Li, Yoonbai Kim, Bum-Hoon Lee +2
This study investigates a black hole surrounded by a cloud of strings and a cosmological dark fluid characterized by a modified Chaplygin-like equation of state (MCDF), $p=Aρ-B/ρ^β…

Spacetime quantization effects on 5-dimensional black string evaporation
Xiang-Qian Li
Spacetime quantization predicts the existence of minimal length and time-interval. Within 5-dimensional Schwarzschild-like black string background, the tunneling of scalar particle…
