Quasi-stationary solutions of self-gravitating scalar fields around black holes
Nicolas Sanchis-Gual, Juan Carlos Degollado, Pedro J. Montero +1
Recent perturbative studies have shown the existence of long-lived, quasi-stationary configurations of scalar fields around black holes. In particular, such configurations have bee…

Fully covariant and conformal formulation of the Z4 system in a reference-metric approach: comparison with the BSSN formulation in spherical symmetry
Nicolas Sanchis-Gual, Pedro J. Montero, Jose A. Font +2
We adopt a reference-metric approach to generalize a covariant and conformal version of the Z4 system of the Einstein equations. We refer to the resulting system as ``fully covaria…
