Gravitational lensing by a stable rotating regular black hole
Chen-Hao Xie, Yu Zhang, Qi Sun +2
Recent observational data from the Event Horizon Telescope (EHT) collaboration provide convincing realistic evidence for the existence of black hole rotation. From a phenomenologic…
Shadow of Kerr black hole surrounded by a cloud of strings in Rastall gravity and constraints from M87*
Qi Sun, Yu Zhang, Chen-Hao Xie +1
Motivated by the first image of a black hole captured by the Event Horizon Telescope (EHT), there has been a surge of research using observations of black hole shadows to test theo…
Rotating and twisting charged black holes with cloud of strings and quintessence as a particle accelerator
Qi-Quan Li, Yu Zhang, Qi Sun +1
In this paper, we study the effects of the rotation parameter , the twist parameter , the string cloud parameter , the quintessence state parameter and the charge…
Thermal fluctuation, deflection angle and greybody factor of a high-dimensional Schwarzschild black hole in STVG
Qian Li, Yu Zhang, Qi-Quan Li +1
In this work, we study the thermal fluctuation, deflection angle and greybody factor of the high-dimensional Schwarzschild black hole in scalar-tensor-vector gravity (STVG). Based…
Weak gravitational lensing by an ESTGB black hole in the presence of a plasma
Qian Li, Yu Zhang, Zhi-Wen Lin +2
This paper is devoted to studying the weak-field gravitational lensing properties of a 4D ESTGB black hole, which is surrounded by the plasma medium. The effects of the magnetic ch…
Rotating Bardeen black hole surrounded by perfect fluid dark matter as a particle accelerator
Qi-Quan Li, Yu Zhang, Qian Li +1
We study the event horizon of a rotating Bardeen black hole surrounded by perfect fluid dark matter and the black hole as a particle accelerator. The black hole is represented by f…
