Higher-dimensional theories admit astrophysical objects like supermassive black holes, which are rather different from standard ones, and their gravitational lensing features deviate general relativity. It is well known that a hole shadow dark region due to the falling geodesics of photons into and, if detected, could be used determine theory gravity consistent with observations. Measurements sizes around holes can help evaluate various parameters metric. We study shapes cast by rotating...

Abstract The photon region surrounding a black hole is crucial for distant observers to receive the emitted spectrum from its vicinity. This paper investigates optical features of regular spinning anti-de Sitter (AdS) hole.
These kinds holes hold deviation parameter $k$, and cosmological constant $\Lambda$ including their mass $M$ spin $a$. depends on curvature radius by $\Lambda = -3/l^2$.
We investigate structure geodesics unstable circular orbits photons as observed an...

We study the shadow cast by H$D$ Schwarzschild-Tangherlini black hole, and analytically calculate influence of extra dimensions on a hole. A hole casts as an optical appearance because its strong gravitational field which is known to be dark zone covered circle for Schwarzschild demonstrate that null geodesic equation can integrated Hamilton-Jacobi approach, enables us investigate holes. Interestingly, it turns out that, fixed values mass parameter, in spacetimes are smaller when compared...

The presence of a photon region around the black hole is an essential feature in receiving emitted spectrum from vicinity by distant observer. In this paper, we investigate optical properties rotating regular anti-de Sitter (AdS) holes, which characterized its mass $(M)$, spin parameter $(a)$, deviation $(k)$ and cosmological constant $(\Lambda)$ related to curvature radius via $(\Lambda=-3/l^2)$. We derive complete null geodesic equations motion study unstable circular orbits for observer...

We investigate the end state of gravitational collapse Husain space‐time in higher dimensional space‐times. Both naked singularities and black holes are shown to be developing as final outcome collapse. Earlier work is generalized space‐times allow a study effect number dimensions on possible terms hole or singularity. No restriction adopted dimensions. These results might important light recent proposal that there may exist extra universe.
