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…
Quasistationary solutions of self-gravitating scalar fields around collapsing stars
Nicolas Sanchis-Gual, Juan Carlos Degollado, Pedro J. Montero +2
Recent work has shown that scalar fields around black holes can form long-lived, quasistationary configurations surviving for cosmological timescales. With this requirement, scalar…
Numerical relativity simulations of thick accretion disks around tilted Kerr black holes
Vassilios Mewes, José A. Font, Filippo Galeazzi +2
In this work we present 3D numerical relativity simulations of thick accretion disks around tilted Kerr BH. We investigate the evolution of three different initial disk models with…
Measuring the black hole spin direction in 3D Cartesian numerical relativity simulations
Vassilios Mewes, José A. Font, Pedro J. Montero
We show that the so-called flat-space rotational Killing vector method for measuring the Cartesian components of a black hole spin can be derived from the surface integral of Weinb…
Numerical Relativity in Spherical Polar Coordinates: Off-center Simulations
Thomas W. Baumgarte, Pedro J. Montero, Ewald Müller
We have recently presented a new approach for numerical relativity simulations in spherical polar coordinates, both for vacuum and for relativistic hydrodynamics. Our approach is b…
