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…
Splitting the Gravitational Atom: Instabilities of Black Holes with Synchronized or Resonant Hair
Jordan Nicoules, José Ferreira, Carlos A. R. Herdeiro +2
Black holes (BHs) with synchronized bosonic hair challenge the Kerr paradigm, linking superradiance from ultralight fields -- creating gravitational atoms -- to bosonic stars acros…
Dancing in the dark: probing Dark Matter through the dynamics of eccentric binary pulsars
Giorgio Nicolini, Andrea Maselli, Miguel Zilhão
We investigate the dynamics of eccentric binary pulsars embedded in dark matter environments. While previous studies have primarily focused on circular orbits in collisionless dark…
Stability and collisions of excited spherical boson stars: glimpses of chains and rings
Marco Brito, Carlos Herdeiro, Eugen Radu +2
Scalar, spherically symmetric, radially excited boson stars were previously shown to be stabilized, against spherical dynamics, by sufficiently strong self-interactions. Here, we f…
