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…
A Circular Disformal Kerr Black Hole
Jibril Ben Achour, Adolfo Cisterna, Hugo Roussille
The Kerr solution is the cornerstone of General Relativity (GR) for modelling astrophysical rotating black holes and for testing GR through gravitational-wave observations and blac…
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…
Magnetized dynamical black holes
Jibril Ben Achour, Adolfo Cisterna, Amaro Díaz +1
We construct a novel exact solution of the Einstein-scalar-Maxwell equations describing a dynamical black hole immersed in an external, time-dependent electromagnetic field. Motiva…
Dynamical axisymmetric compact objects in General Relativity
Jibril Ben Achour, Adolfo Cisterna, Mokhtar Hassaine
The search for exact solutions describing asymptotically FLRW compact objects in General Relativity remains a challenging problem. Progress has largely been limited to the spherica…
