Shadows and Polarization Images of a Four-dimensional Gauss-Bonnet Black Hole Irradiated by a Thick Accretion Disk
Xiao-Xiong Zeng, Huan Ye, Muhammad Israr Aslam +1
We adopt a general relativistic ray-tracing approach to study the shadows and polarization images of spherically symmetric Gauss-Bonnet (GB) black holes enveloped by geometrically…
Imaging and polarization patterns of various thick disks around Kerr-MOG black holes
Xinyu Wang, Huan Ye, Xiao-Xiong Zeng
We investigate the imaging and polarization properties of Kerr-MOG black holes surrounded by geometrically thick accretion flows. The MOG parameter introduces deviations from…
Shadow and Polarization Images of Rotating Black Holes in Kalb-Ramond Gravity Illuminated by Several Thick Accretion Disks
Chen-Yu Yang, Huan Ye, Xiao-Xiong Zeng
Using ray-tracing techniques, this paper investigates the optical and polarization images of rotating black holes in Kalb-Ramond (KR) gravity illuminated by thick accretion disks.…
Observational features of the Bardeen-boson star with thin disk accretion
Chen-Yu Yang, Huan Ye, Xiao-Xiong Zeng
In this work, we construct spherically symmetric solutions of Bardeen--boson stars within the framework of the Einstein--Klein--Gordon theory coupled to nonlinear electrodynamics b…
Optical images of massive boson stars with nonlinear electrodynamics
Xiao-Xiong Zeng, Huan Ye, Ke-Jian He +1
This study investigates the optical imaging characteristics of massive boson stars based on a model with Einstein's nonlinear electrodynamics. Under asymptotically flat boundary co…
Holographic Einstein Ring of Deformed AdS-Schwarzschild Black Holes
Jin-Yu Gui, Xiao-Xiong Zeng, Ke-Jian He +1
In this work, the wave optics is employed to investigate the Einstein ring of a deformed AdS-Schwarzschild black hole (BH). When the source is fixed on the AdS boundary, one can ob…
