Accelerated Reissner-Nordstrom black hole in a swirling, magnetic universe

TL;DR

This paper introduces a new exact solution in Einstein's relativity describing an accelerated Reissner-Nordström black hole in a magnetic, rotating universe, analyzing its physical properties and regularization.

Contribution

It presents a novel exact solution using Ernst symmetries, combining acceleration, charge, and magnetic rotation in a unified spacetime model.

Findings

Derived a new metric for accelerated charged black holes in magnetic universes.

Analyzed conical singularities and ergoregions of the solution.

Explored regularization of the spacetime to address singularities.

Abstract

We present a new solution in Einstein's theory of relativity, found through the use of the symmetries of the Ernst equations and in particular the Harrison and Ehlers transformations. The new metric represents a Reissner-Nordstr\"om black hole immersed in a magnetic, rotating universe. We analyse the physical properties, such as conical singularities and ergoregions, and then proceed to immerse the accelerated version of the Reissner-Nordstr\"om black hole in the same background. We finally analyse its properties and attempt to regularise the spacetime.
