We argue that the complex transformation relating the Schwarzschild to the Taub-NUT
metric, introduced by Talbot, is in fact an electric-magnetic duality transformation. We show …

In this review we present the most general form of the Janis–Newman algorithm. This
extension allows generating configurations which contain all bosonic fields with spin less …

Obtaining solutions of the Einstein field equations describing spinning compact bodies is
typically challenging. The Newman–Janis algorithm provides a procedure to obtain rotating …

In this work we derived a rotating and nonlinear magnetic-charged black hole surrounded by
quintessence using the Newman-Janis algorithm. Considering the state parameter ω q=-3/2 …

This paper exploits the power of the Cayley–Dickson algebra to generate stationary rotating
black hole solutions in one fell swoop. Specifically, we derive the nine-dimensional Myers …

Higher-dimensional theories admit that astrophysical objects like supermassive black holes
are somewhat different from standard ones and that their optical properties deviate from …

We address a specific issue of the Newman-Janis algorithm: determining the general form of
the complex transformation for the Schwarzschild metric and ensuring that the resulting …

A bstract The Lense-Thirring spacetime describes a 4-dimensional slowly rotating
approximate solution of vacuum Einstein equations valid to a linear order in rotation …

We derive a rotating counterpart of the five-dimensional electrically charged Bardeen
regular black holes spacetime by employing the Giampieri algorithm on static one. The …

The Newman–Janis trick is a procedure,(not even really an ansatz), for obtaining the Kerr
spacetime from the Schwarzschild spacetime. This 50 years old trick continues to generate …
