Rotating black holes with primary hair in five-dimensional generalized Proca theory
Mokhtar Hassaine, Ulises Hernandez-Vera
This work presents a new class of exact analytic rotating black hole solutions within five-dimensional generalized Proca theories. Through a Kerr-Schild ansatz where the Proca fiel…
An effective cosmological constant as black hole primary hair
Christos Charmousis, Pedro G. S. Fernandes, Mokhtar Hassaine
We study Generalized Proca theories inspired by the recent regularised Proca theory of four-dimensional Gauss-Bonnet gravity. By abandoning the rigid constraints typically imposed…
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…
Ultrarelativistic limit of the Kerr theorem
Eloy Ayón-Beato, Daniel Flores-Alfonso, Mokhtar Hassaine
The original Kerr theorem provides the foundation for Kerr-Schild transformations by classifying all shear-free and geodesic null congruences in flat spacetime; the key ingredient…
Cardy Entropy of Charged and Rotating Asymptotically AdS and Lifshitz Solutions with a Generalized Chern-Simons term
Moises Bravo-Gaete, Adolfo Cisterna, Mokhtar Hassaine +1
We consider a three-dimensional gravity model that includes (non-linear) Maxwell and Chern-Simons-like terms, allowing for the existence of electrically charged rotating black hole…
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…
