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 discs are prone to a global non-axisymmetric hydrodynamic instability,

Quasistationary solutions of scalar fields around accreting black holes

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 regimes. In this paper we show that quasi-bound states can form in a dyna

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 particles in the disc which are advected with the flow. Such tracers, whic

Dynamics of magnetized relativistic tori oscillating around black holes

Autor: Olindo Zanotti, José A. Font, Pedro J. Montero, Luciano Rezzolla

Publikováno v: Monthly Notices of the Royal Astronomical Society

We present a numerical study of the dynamics of magnetized, relativistic, non-self-gravitating, axisymmetric tori orbiting in the background spacetimes of Schwarzschild and Kerr black holes. The initial models have a constant specific angular momentu

Quasistationary solutions of self-gravitating scalar fields around collapsing stars

Autor: Juan Carlos Degollado, Vassilios Mewes, Pedro J. Montero, José A. Font, Nicolas Sanchis-Gual

Recent work has shown that scalar fields around black holes can form long-lived, quasistationary configurations surviving for cosmological time scales. Scalar fields thus cannot be discarded as viable candidates for dark matter halo models in galaxie
