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…
Optical appearance of the Konoplya-Zhidenko rotating non-Kerr black hole surrounded by a thin accretion disk
Ke-Jian He, Yi Liu, Chen-Yu Yang +1
In this study, we investigate the optical appearance of rotating Konoplya-Zhidenko non-Kerr black holes in the presence of thin accretion disks, with the aim of examining whether t…
Shadow Images of Ghosh-Kumar Rotating Black Hole Illuminated By Spherical Light Sources and Thin Accretion Disks
Chen-Yu Yang, M. Israr Aslam, Xiao-Xiong Zeng +1
This study investigates the astronomical implications of the Ghosh-Kumar rotating Black Hole (BH), particularly its behaviour on shadow images, illuminated by celestial light sourc…
Observational features of the rotating Bardeen black hole surrounded by perfect fluid dark matter
Ke-Jian He, Guo-Ping Li, Chen-Yu Yang +1
By employing ray-tracing techniques, we investigate the shadow images of rotating Bardeen black holes surrounded by perfect fluid dark matter. In this work, two models are consider…
