Multipole moments on the common horizon in a binary-black-hole simulation
Yitian Chen, Prayush Kumar, Neev Khera +8
We construct the covariantly defined multipole moments on the common horizon of an equal-mass, non-spinning, quasicircular binary-black-hole system. We see a strong correlation bet…
Nonlinearities in Black Hole Ringdowns
Keefe Mitman, Macarena Lagos, Leo C. Stein +11
The gravitational wave strain emitted by a perturbed black hole (BH) ringing down is typically modeled analytically using first-order BH perturbation theory. In this Letter we show…
Fixing the BMS frame of numerical relativity waveforms with BMS charges
Keefe Mitman, Leo C. Stein, Michael Boyle +8
The Bondi-van der Burg-Metzner-Sachs (BMS) group, which uniquely describes the symmetries of asymptotic infinity and therefore of the gravitational waves that propagate there, has…
Quasinormal-mode filters: a new approach to analyze the gravitational-wave ringdown of binary black-hole mergers
Sizheng Ma, Keefe Mitman, Ling Sun +7
We propose two frequency-domain filters to analyze ringdown signals of binary black hole mergers. The first rational filter is constructed based on a set of (arbitrary) quasi-norma…
Gravitational-wave echoes from numerical-relativity waveforms via space-time construction near merging compact objects
Sizheng Ma, Qingwen Wang, Nils Deppe +7
We propose a new approach toward reconstructing the late-time near-horizon geometry of merging binary black holes, and toward computing gravitational-wave echoes from exotic compac…
