Gravitational wave signatures of massive scalar fields around black holes |
|
Abstract |
We examine how the gravitational wave signal of a perturbed black hole is affected by quasibound configurations of scalar fields. Solving the Teukolsky equation for gravitational perturbations of a black hole coupled to the Klein-Gordon equation, we find a characteristic gravitational wave signal, composed by a quasi-normal ringing followed by a late time tail. We find that the late time tail contains small amplitude wiggles with the frequency of the dominating quasibound scalar state. |
