Reconstruction of the Weyl-Lewis-Papapetrou metric for stationary and axially symmetric gravitational perturbations of a Kerr black hole
David Kofroň, Petr Kotlařík
The study of black hole perturbations typically follows two main approaches: the direct perturbation of the metric, or the perturbation within the Newman-Penrose (NP) or Geroch-Hel…

Quasinormal modes of black holes encircled by a gravitating thin disk
Che-Yu Chen, Petr Kotlařík
The ringdown phase of gravitational waves emitted by a perturbed black hole is described by a superposition of exponentially decaying sinusoidal modes, called quasinormal modes (QN…

Black hole encircled by a thin disk: fully relativistic solution
Petr Kotlařík, David Kofroň
We give a full metric describing the gravitational field of a static and axisymmetric thin disk without radial pressure encircling a Schwarzschild black hole. The disk density prof…
