Imaging higher-dimensional black objects.

We develop a systematic ray-tracing method which can be used to explore a wide class of higher-dimensional multicenter 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.
