DOI: 10.1103/physrevd.102.024007
Abstract: Ringdown gravitational waves of compact binary mergers are an important target to test general relativity. The main components of the ringdown waveform after merger are black hole quasinormal modes. In general relativity, all multipolar quasinormal… read more here.

DOI: 10.1103/physrevd.107.083021
Abstract: Black-hole spectroscopy, that is, measuring the characteristic frequencies and damping times of different modes in a black-hole ringdown, is a powerful probe for testing deviations from the general theory of relativity (GR). In this work,… read more here.

DOI: 10.1103/physrevd.99.104082
Abstract: We investigate the prospect of using black hole spectroscopy to constrain the parameters of Horndeski gravity through observations of gravitational waves from perturbed black holes. We study the gravitational waves emitted during ringdown from black… read more here.

DOI: 10.1103/physrevd.99.124043
Abstract: The early inspiral of massive stellar-mass black-hole binaries merging in LIGO’s sensitivity band will be detectable at low frequencies by the upcoming space mission LISA. LISA will predict, with years of forewarning, the time and… read more here.
