From Accelerating Rotating Black Holes to a Swirling Universe
José Barrientos, Adolfo Cisterna
We demonstrate that the swirling universe can be recovered through a coordinated horizon-degeneration and scaling procedure applied to the Kerr C-metric. The construction exploits…
From Bertotti--Robinson to Vacuum: New Exact Solutions in General Relativity via Harrison and Inversion Symmetries
José Barrientos, Adolfo Cisterna, Amaro Díaz +1
We construct new vacuum solutions of the Einstein equations generated from electrovacuum configurations embedded in external electromagnetic backgrounds. Starting from accelerating…
Melvin--Bonnor and Bertotti--Robinson spacetimes with Baryonic charge
José Barrientos, Fabrizio Canfora, Adolfo Cisterna +2
In this work, we exploit a dictionary that maps solutions of the Einstein--Scalar--Maxwell theory to those of gauged Skyrme--Maxwell--Einstein models in dimensions, allowin…

José Barrientos, Adolfo Cisterna, Mokhtar Hassaine +2
We construct a new rotating solution of Einstein's theory in vacuum by exploiting the Lie point symmetries of the field equations in the complex potential formalism of Ernst. In pa…

José Barrientos, Nicolás Cáceres, Felipe Diaz +1
We study magnetotransport in a holographic model where ModMax nonlinear electrodynamics is coupled to Einstein anti--de Sitter gravity. To incorporate momentum relaxation, we intro…

Marcello Ortaggio, Jakub Voldřich, José Barrientos
We present a complete, theory-independent classification of -dimensional Kundt spacetimes of Weyl and traceless-Ricci type N. We show that these geometries consist of three inva…

José Barrientos, Adolfo Cisterna, Ivan Kolář +3
In this paper, we obtain a complete list of stationary and axisymmetric spacetimes, generated from a Minkowski spacetime using the Ernst technique. We do so by operating on the ass…
Plebanśki-Demiański à la Ehlers-Harrison: Exact Rotating and Accelerating Type I Black Holes
