4-OGC: Catalog of gravitational waves from compact-binary mergers
Alexander H. Nitz, Sumit Kumar, Yi-Fan Wang +5
We present the fourth Open Gravitational-wave Catalog (4-OGC) of binary neutron star (BNS), binary black hole (BBH) and neutron star-black hole (NSBH) mergers. The catalog includes…
Model systematics in time domain tests of binary black hole evolution
Shilpa Kastha, Collin D. Capano, Julian Westerweck +3
We perform several consistency tests between different phases of binary black hole dynamics; the inspiral, the merger, and the ringdown on the gravitational wave events GW150914 an…
Linear momentum flux from inspiralling compact binaries in quasi-elliptical orbits at 2.5 Post-Newtonian order
Shilpa Kastha
Emission of anisotropic gravitational radiation from compact binary system leads to a flux of linear momentum. This results in the recoil of the system. We investigate the rate of…
3-OGC: Catalog of gravitational waves from compact-binary mergers
Alexander H. Nitz, Collin D. Capano, Sumit Kumar +5
We present the third Open Gravitational-wave Catalog (3-OGC) of compact-binary coalescences, based on the analysis of the public LIGO and Virgo data from 2015 through 2019 (O1, O2,…
A multimode quasi-normal spectrum from a perturbed black hole
Collin D. Capano, Miriam Cabero, Julian Westerweck +6
When two black holes merge, the late stage of gravitational wave emission is a superposition of exponentially damped sinusoids. According to the black hole no-hair theorem, this ri…
