Shadow of five-dimensional rotating Myers-Perry black hole

TL;DR

This paper investigates the shadow of a five-dimensional Myers-Perry black hole with equal rotation parameters, revealing how rotation affects the shadow's shape and size compared to four-dimensional black holes.

Contribution

It provides the first detailed analysis of the shadow of a five-dimensional Myers-Perry black hole, including effects of rotation on its shape and size.

Findings

Shadow becomes more distorted with increased spin.

Shadow size decreases as black hole spin increases.

Compared to four-dimensional Kerr black holes, the five-dimensional shadow is smaller and less deformed.

Abstract

A black hole casts a shadow as an optical appearance because of its strong gravitational field. We study the shadow cast by the five-dimensional Myers-Perry black hole with equal rotation parameters. We demonstrate that the null geodesic equations can be integrated that allows us to investigate the shadow cast by a black hole. The shadow of a black hole is found to be a dark zone covered by deformed circle. Interestingly, the shapes of the black hole shadow are more distorted and size decreases for larger black hole spins. Interestingly, it turns out that, for fixed values of rotation parameter, the shadow is slightly smaller and less deformed than for its four-dimensional Kerr black counterpart. Further, the shadow of the five-dimensional Kerr black hole is concentric deformed circles. The effect of rotation parameter on the shape and size of a naked singularity shadow is also analyzed.
