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…
Electromagnetic partner of the gravitational signal during accretion onto black holes
Juan Carlos Degollado, Victor Gualajara, Claudia Moreno +1
We investigate the generation of electromagnetic and gravitational radiation in the vicinity of a perturbed Schwarzschild black hole. The gravitational perturbations and the electr…
Wiggly tails: a gravitational wave signature of massive fields around black holes
Juan Carlos Degollado, Carlos A. R. Herdeiro
Massive fields can exist in long-lived configurations around black holes. We examine how the gravitational wave signal of a perturbed black hole is affected by such `dirtiness' wit…
