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…
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…
Into the MAG-verse or: Cosmology of the Complete Quadratic Metric-Affine Gravity
Damianos Iosifidis, Konstantinos Pallikaris
We study the cosmology of the complete quadratic (in torsion and nonmetricity) metric-affine gravity. Namely, we add to the scalar-curvature gravitational Lagrangian, the 17 indepe…
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…
Exact rotating wormholes via Ehlers transformations
Adolfo Cisterna, Keanu Müller, Konstantinos Pallikaris +1
In this paper, we construct exact rotating wormholes using Ehlers solution-generating technique. This is based on the Ernst description of four-dimensional, stationary, and axially…
