Shadows of 5D black holes from string theory

We study the shadow behaviors of five dimensional (5D) black holes embedded in type IIB superstring/supergravity inspired spacetimes by considering solutions with and without rotations. Geometrical properties as shapes and sizes are analyzed in terms of the D3-brane number and the rotation parameter. Concretely, we find that the shapes are indeed significantly distorted by such physical parameters and the size of the shadows decreases with the brane or color number and the rotation. Then, we investigate geometrical observables and energy emission rate aspects. (C) 2020 Published by Elsevier B.V.

Automated summary

This study investigates the shadow behaviors of five dimensional black holes embedded in type IIB superstring/supergravity inspired spacetimes, analyzing geometrical properties such as shapes and sizes. It is found that physical parameters significantly distort the shapes and decrease the size of the shadows. The research also delves into geometrical observables and energy emission rate aspects.
