Constraints on Shadow Radius and Instabilities Arising from Various Perturbations in Spherically Symmetric Black Holes in Einstein-power-Yang-Mills-Gauss-Bonnet Gravity
Zening Yan
The space-time geometry under investigation is chosen to be a high-dimensional, static, spherically symmetric solution in an asymptotically flat background within the Einstein-powe…

Standard constraints on the shadow radius of black holes in -dimensional space-time: The case of regular Einstein-Gauss-Bonnet solutions
Zening Yan
In this work, we propose a -dimensional constraint formula for the black hole shadow radius, providing a standardized framework for using observational confidence intervals to c…

Employing shadow radius to constrain extra dimensions in black string space-time with dark matter halo
Zening Yan
We study the shadow of five-dimensional black strings immersed in dark matter environment. We show the influence of the momentum characteristic parameter of the…
