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…
Shadow, absorption and Hawking radiation of a Schwarzschild black hole surrounded by a cloud of strings in Rastall gravity
Qian Li, Chen Ma, Yu Zhang +2
This paper studies the black hole shadow, absorption cross section, and Hawking radiation of a massless scalar field in the background of a static spherically symmetric black hole…
Gray-body factor and absorption of the Dirac field in ESTGB gravity
Qian Li, Chen Ma, Yu Zhang +2
The gray-body factor and the absorption cross section of the 4D ESTGB gravity with a mode of nonlinear electrodynamics for the massless Dirac field are studied in this paper. The m…
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…
