Shadows of rotating black holes in alternative theories

TL;DR

This paper reviews recent progress in understanding the shadows of rotating black holes within alternative theories, highlighting how their size and shape vary with different parameters, including specific models like rotating braneworld black holes.

Contribution

It provides a concise overview of how black hole shadows are affected by alternative theories and presents specific results for rotating braneworld black holes.

Findings

Shadow size and shape depend on mass, angular momentum, and model-specific parameters.

Rotating braneworld black holes exhibit distinct shadow features.

Recent advances enhance understanding of observational signatures of alternative gravity models.

Abstract

We briefly review some recent advances in the study of the shadows of rotating black holes in alternative theories. The size and the shape of the shadow depend on the mass and the angular momentum, and they can also depend on other parameters specific of the particular model adopted. As an example, we show the results corresponding to a rotating braneworld black hole.
