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

Understand

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.
