Dynamical formation of a hairy black hole in a cavity from the decay of unstable solitons
Nicolas Sanchis-Gual, Juan Carlos Degollado, José A. Font +2
Recent numerical relativity simulations within the Einstein--Maxwell--(charged-)Klein-Gordon (EMcKG) system have shown that the non-linear evolution of a superradiantly unstable Re…
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…
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…
