Turbulent gravitational wakes
Giulio Taiocchi, Christiana Pantelidou, Miguel Zilhão
We construct turbulent gravitational wakes in asymptotically AdS spacetimes by solving the full non-linear Einstein equations in the characteristic formulation. Specifically, w…
Electromagnetic duality degeneracy in dynamical black hole mergers
José Ferreira, Gabriele Bozzola, Carlos A. R. Herdeiro +2
Electromagnetic duality is a symmetry of the source-free Einstein-Maxwell equations that rotates electric and magnetic fields while leaving the stress-energy tensor invariant. We p…
Spontaneous spherical symmetry breaking of black holes with resonant hair
José Ferreira, Carlos A. R. Herdeiro, Eugen Radu +1
Black holes with resonant hair are static, spherical, electrically charged solutions of the Einstein-Maxwell-(gauged-)scalar system. Scalar self-interactions are mandatory for thei…
