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…
Displacement versus velocity memory effects from a gravitational plane wave
Jibril Ben Achour, Jean-Philippe Uzan
This article demonstrates that additionally to the well-known velocity memory effect, a vacuum gravitational plane wave can also induce a displacement memory on a couple of test pa…
Quadratic perturbations of the Schwarzschild black hole: The algebraically special sector
Jibril Ben Achour, Hugo Roussille
We investigate quadratic algebraically special perturbations (ASPs) of the Schwarzschild black hole. Their dynamics are derived from the expansion up to second order in perturbatio…
