Abstract: Black hole perturbation theory for Kerr black holes is best studied in the Newman Penrose (NP) Formalism, in which gravitational waves are described as perturbations in the Weyl scalars ψ0 and ψ4, with the governing… read more here.

Abstract: Existing constraints on the graviton mass from gravitational-wave detections rely on the phase difference developed between different frequencies during the propagation. Effects on the quasinormal-mode frequencies of the black-hole ringdown due to the graviton mass… read more here.

DOI: 10.1103/physrevx.13.021029
Abstract: The detection of gravitational waves from compact binary mergers by the LIGO/Virgo collaboration has, for the first time, allowed for tests of relativistic gravity in the strong, dynamical and nonlinear regime. Outside Einstein's relativity, spinning… read more here.
