General Concentric Black Rings

TL;DR

This paper constructs supersymmetric black ring solutions in five-dimensional supergravity, describing concentric rings with regular horizons and no closed time-like curves, expanding understanding of higher-dimensional black objects.

Contribution

It provides the first explicit construction of supersymmetric concentric black rings in five-dimensional supergravity with arbitrary vector multiplets.

Findings

Solutions are asymptotically flat.

Black rings have $S^1 imes S^2$ topology.

Horizons are regular with no closed time-like curves.

Abstract

Supersymmetric black ring solutions of five dimensional supergravity coupled to an arbitrary number of vector multiplets are constructed. The solutions are asymptotically flat and describe configurations of concentric black rings which have regular horizons with topology $S^1 \times S^2$ and no closed time-like curves at the horizons.
