Probing Horndeski Gravity via Kerr Black Hole: Insights from Thin Accretion Disks and Shadows with EHT Observations
Xiao-Xiong Zeng, Chen-Yu Yang, M. Israr Aslam +1
In this study, we have considered the Kerr-like black hole (BH) model in Horndeski gravity and analyse the visual characteristics of shadow images under two illumination models, su…
Optical Characteristics of the Kerr-Bertotti-Robinson Black Hole
Xiao-Xiong Zeng, Chen-Yu Yang, Hao Yu
The Kerr-Bertotti-Robinson (Kerr-BR) black hole, a theoretical model of a rotating black hole immersed in a uniform magnetic field, has been proposed recently by Podolsky and Ovcha…
Kerr-like Black Hole Surrounded by Cold Dark Matter Halo: The Shadow Images and EHT Constraints
Xiao-Xiong Zeng, Chen-Yu Yang, M. Israr Aslam +2
Here we provide shadow images of a Kerr-like black hole (BH) in cold dark matter (CDM) halo illuminated with a celestial light source and a thin accretion disk. The impact of spin…
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…
