Shadows and amplitude luminosity of an embedded rotating black hole

Le résumé fourni par la source

We investigate a rotating black hole embedded in a five-dimensional flat bulk by extending the Kerr metric through the Gurses-Gursey line element. Employing Boyer-Lindquist coordinates, we reinterpret the black hole as a charged-like object in five dimensions and analyze its horizon structure and shadow morphology. Our results reveal that the shadow is shaped by an axially symmetric gravitational field modulated by an extrinsic curvature term arising from the higher-dimensional embedding. Simulations demonstrate that the visibility amplitude and shadow profile of the Gurses-Gursey black hole align with Event Horizon Telescope observations of M87 in the Kerr limit, while also allowing measurable deviations that could be probed by future high-resolution experiments.
