Gravitational lensing and observational features of a dynamic black hole
Ke-Jian He, Guo-Ping Li, Li-Fang Li +1
In this work, we investigate the gravitational lensing effects and the dynamic evolution of the shadow of Vaidya black holes by employing backward ray-tracing techniques. Within th…
Energy Extraction from Rotating Charged Black Holes in Kalb-Ramond Gravity
Jin-Tao Yao, Ke-Jian He, Zi-Chao Lin +1
This work presents a comprehensive study of energy extraction via the Comisso-Asenjo magnetic reconnection mechanism from rotating charged black holes in the context of Kalb-Ramond…
Probing Observable Features of Lorentz violation in Low-Energy Hořava Gravity with Accretion Disk Images of Black Hole
Meng-Die Zhao, Yu-Yan Wang, Ke-Jian He +1
In this paper, we study the observable signatures of Lorentz violation (LV) in low-energy Horava gravity by simulating the images and polarization features of rotating LV black hol…
Observational features of massive boson stars with thin disk accretion
Guo-Ping Li, Meng-Qi Wu, Ke-Jian He +1
In this paper, based on the action of a complex scalar field minimally coupled to a gravitational field, we numerically obtain a series of massive boson star solutions in a spheric…
A Novel Jet Model for the Novikov-Thorne Disk and its Observable Impact
Sen Guo, Pei Wang, Ke-Jian He +3
Recent high-resolution observations have established a strong link between black hole jets and accretion disk structures, particularly in the 3.5 mm wavelength band [Nature. 616, 6…
Triple points and phase transitions of D-dimensional dyonic AdS black holes with quasitopological electromagnetism in Einstein-Gauss-Bonnet gravity
Ping-Hui Mou, Qing-Quan Jiang, Ke-Jian He +1
By considering the negative cosmological constant Λ as a thermodynamic pressure, we study the thermodynamics and phase transitions of the D-dimensional dyonic AdS black holes (BHs)…
The feature of shadow images and observed luminosity of the Bardeen black hole surrounded by different accretions
Ke-Jian He, Sen Guo, Shuang-Cheng Tan +1
In this paper, by exploring the photon motion in the region near the Bardeen black hole, the shadow and observation properties of the black hole surrounded by various accretion mod…
Hayward black hole heat engine efficiency in anti-de Sitter space
Sen Guo, Ya-Ling Huang, Ke-Jian He +1
In this paper, we attempt to further study the heat engine efficiency for the regular black hole (BH) with an anti-de Sitter (AdS) background where the working material is the Hayw…
