Black strings in asymptotically plane wave geometries

TL;DR

This paper introduces a new class of black string solutions that asymptote to plane wave geometries, constructed using the null Melvin twist, which preserves the event horizon while deforming the spacetime.

Contribution

The authors develop a solution generating method to produce asymptotically plane wave black strings from flat black strings, expanding the landscape of known black string solutions.

Findings

Constructed explicit black string solutions asymptotic to plane wave geometries.

Demonstrated the null Melvin twist preserves the event horizon.

Provided a new approach to generate black objects in non-flat backgrounds.

Abstract

We present a class of black string spacetimes which asymptote to maximally symmetric plane wave geometries. Our construction will rely on a solution generating technique, the null Melvin twist, which deforms an asymptotically flat black string spacetime to an asymptotically plane wave black string spacetime while preserving the event horizon.
