Polarization images of non-topological soliton Bardeen boson stars
Xiao-Xiong Zeng, Chen-Yu Yang, Ke-Jian He +1
In this study, we investigate the polarized images of non-topological soliton Bardeen boson stars by solving the coupled Einstein nonlinear electrodynamics complex scalar field equ…
Horizon-scale intensity and polarization images of rotating Konoplya-Zhidenko black holes with thick accretion flows
Bing-Bing Chen, Chen-Yu Yang, Guo-Ping Li +1
We investigate the shadow and polarization images of a Konoplya-Zhidenko rotating non-Kerr black hole surrounded by a geometrically thick and optically thin accretion flow. The acc…
Distinguishing Black Holes and Neutron Stars via Optical Images Illuminated by Thick Accretion Disks
Chen-Yu Yang, Xiao-Xiong Zeng
This paper investigates the optical images of neutron stars within the framework of the radiatively inefficient accretion flow model, taking into account a polytropic equation of s…
Imprints of Black Hole Shadows and Polarization Patterns of Various Thick Disks: Bumblebee gravity
Muhammad Israr Aslam, Nazek Alessa, Chen-Yu Yang +1
The main objective of this study is to explore the shadow and polarization patterns of a Kerr-Sen-like BH induced from Bumblebee gravity, which, among other alternative theories of…
Optical images of Kerr-Sen black hole illuminated by thick accretion disks
Yu-Kang Wang, Chen-Yu Yang, Xiao-Xiong Zeng
This paper investigates the shadow and polarization images of a Kerr-Sen black hole illuminated by geometrically thick and optically thin accretion disks. We adopt two classes of a…
Unveiling Inner Shadows and Polarization Signatures of Rotating Einstein-Gauss-Bonnet Black Holes
Bing-Bing Chen, Chen-Yu Yang, Deyou Chen +1
Based on the backward ray-tracing method, this paper numerically investigates the shadow and polarization images of rotating Einstein-Gauss-Bonnet (EGB) black hole within the frame…
