Papaloizou-Pringle instability suppression by the magnetorotational instability in relativistic accretion discs
Matteo Bugli, Jérôme Guilet, Ewald Müller +3
Geometrically thick tori with constant specific angular momentum have been widely used in the last decades to construct numerical models of accretion flows onto black holes. Such d…
Dynamical formation of a Reissner-Nordström black hole with scalar hair in a cavity
Nicolas Sanchis-Gual, Juan Carlos Degollado, Carlos Herdeiro +2
In a recent letter, we presented numerical relativity simulations, solving the full Einstein--Maxwell--Klein-Gordon equations, of superradiantly unstable Reissner-Nordström black h…
On the dynamics of tilted black hole-torus systems
Vassilios Mewes, Filippo Galeazzi, José A. Font +2
We present results from three-dimensional, numerical relativity simulations of a {\it tilted} black hole-thick accretion disc system. The simulations are analysed using tracer part…
Quasistationary solutions of scalar fields around accreting black holes
Nicolas Sanchis-Gual, Juan Carlos Degollado, Paula Izquierdo +2
Massive scalar fields can form long-lived configurations around black holes. These configurations, dubbed quasi-bound states, have been studied both in the linear and nonlinear reg…
Explosion and final state of an unstable Reissner-Nordstrom black hole
Nicolas Sanchis-Gual, Juan Carlos Degollado, Pedro J. Montero +2
A Reissner-Nordström black hole (BH) is superradiantly unstable against spherical perturbations of a charged scalar field, enclosed in a cavity, with frequency lower than a critica…
Critical phenomena in the aspherical gravitational collapse of radiation fluids
Thomas W. Baumgarte, Pedro J. Montero
We study critical phenomena in the gravitational collapse of a radiation fluid. We perform numerical simulations in both spherical symmetry and axisymmetry, and observe critical sc…
