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…
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 DÃaz +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…
From Bertotti--Robinson to Vacuum: New Exact Solutions in General Relativity via Harrison and Inversion Symmetries
José Barrientos, Adolfo Cisterna, Amaro DÃaz +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…
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…
