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…
A new exact rotating spacetime in vacuum: The Kerr--Levi-Civita Spacetime
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…
Rotating spacetimes with a free scalar field in four and five dimensions
José Barrientos, Christos Charmousis, Adolfo Cisterna +1
We construct explicit rotating solutions in Einstein's theory of relativity with a minimally coupled free scalar field rederiving and finding solutions in four or five spacetime di…
Electromagnetized black holes and swirling backgrounds in nonlinear electrodynamics: The ModMax case
José Barrientos, Adolfo Cisterna, Mokhtar Hassaine +1
This work focuses on constructing electromagnetized black holes and vortex-like backgrounds within the framework of the ModMax theory--the unique nonlinear extension of Maxwell's t…
All non-expanding gravitational waves in -dimensional (anti-)de Sitter space
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…
Revisiting Buchdahl transformations: New static and rotating black holes in vacuum, double copy, and hairy extensions
José Barrientos, Adolfo Cisterna, Mokhtar Hassaine +1
This paper investigates Buchdahl transformations within the framework of Einstein and Einstein-Scalar theories. Specifically, we establish that the recently proposed Schwarzschild-…
Mixing "Magnetic'' and "Electric'' Ehlers--Harrison transformations: The Electromagnetic Swirling Spacetime and Novel Type I Backgrounds
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
José Barrientos, Adolfo Cisterna, Konstantinos Pallikaris
Recently, it was shown that type D black holes, encompassed in the large Plebanśki--Demiański (PD) family, exhibit a wide class of algebraically general generalizations via the app…
Ehlers transformations as a tool for constructing accelerating NUT black holes
Jose Barrientos, Adolfo Cisterna
This paper investigates the integrability properties of Einstein's theory of gravity in the context of accelerating Newman-Unti-Tamburino (NUT) spacetimes by utilizing Ernst's desc…
Joule-Thomson expansion of AdS black holes in quasi-topological electromagnetism
José Barrientos, José Mena
We study the Joule-Thomson expansion in Einstein-Maxwell theory supplemented with the so-called quasitopological electromagnetism, this in the extended phase space thermodynamic ap…
Accelerated Black Holes beyond Maxwell's Electrodynamics
Jose Barrientos, Adolfo Cisterna, David Kubiznak +1
Theories of non-linear electrodynamics naturally describe deviations from Maxwell's theory in the strong field regime. Among these, of special interest is the recently discovered M…
Luminal Propagation of Gravitational Waves in Scalar-tensor Theories: The Case for Torsion
José Barrientos, Fabrizio Cordonier-Tello, Cristóbal Corral +4
Scalar-tensor gravity theories with a nonminimal Gauss-Bonnet coupling typically lead to an anomalous propagation speed for gravitational waves, and have therefore been tightly con…
Wave Operators, Torsion, and Weitzenböck Identities
José Barrientos, Fernando Izaurieta, Eduardo Rodríguez +1
We offer a mathematical toolkit for the study of waves propagating on a background manifold with nonvanishing torsion. Examples include electromagnetic and gravitational waves on a…
Nonminimal couplings, gravitational waves, and torsion in Horndeski's theory
José Barrientos, Fabrizio Cordonier-Tello, Fernando Izaurieta +4
The Horndeski Lagrangian brings together all possible interactions between gravity and a scalar field that yield second-order field equations in four-dimensional spacetime. As orig…
