# Imaging Higher Dimensional Black Objects

## TL;DR

This paper introduces a ray-tracing method to visualize higher-dimensional black objects, revealing new phenomena like toroidal horizons and providing insights into black hole structures in multiple dimensions.

## Contribution

The authors develop a systematic ray-tracing technique to image higher-dimensional black objects, including black rings and toroidal horizons, enhancing understanding of their shapes and properties.

## Key findings

- First image of a toroidal horizon
- Revealed new phenomena in higher-dimensional black objects
- Provided a new perspective on black holes and binaries in four dimensions

## Abstract

We develop a systematic ray-tracing method which can be used to explore a wide class of higher-dimensional multi-center black objects through the shape of their shadows. As a proof of principle, we test our method by imaging black holes and black rings in five dimensions. Two-dimensional slices of the three-dimensional shadows of those five-dimensional black objects not only show new phenomena, such as the first image of a toroidal horizon, but also offer a new viewpoint on black holes and binary systems in four dimensions.
