Black holes with bottle-shaped horizons

TL;DR

This paper introduces a new class of four-dimensional AdS black holes with bottle-shaped, non-compact event horizons of finite area, expanding the understanding of black hole horizon topologies.

Contribution

It presents the discovery of black bottle solutions as a special case of the Plebanski-Demianski metric, including static and rotating cases, and explores their full parameter space.

Findings

Black bottle horizons are topologically spheres with a puncture at infinity.

Rotating black bottles include previously known solutions as special limits.

The solution can feature an acceleration horizon under certain parameters.

Abstract

We present a new class of four-dimensional AdS black holes with non-compact event horizons of finite area. The event horizons are topologically spheres with one puncture, with the puncture pushed to infinity in the form of a cusp. Because of the shape of their event horizons, we call such black holes "black bottles". The solution was obtained as a special case of the Plebanski-Demianski solution, and may describe either static or rotating black bottles. For certain ranges of parameters, an acceleration horizon may also appear in the space-time. We study the full parameter space of the solution, and the various limiting cases that arise. In particular, we show how the rotating black hole recently discovered by Klemm arises as a special limit.
