Setting the cornerstone for the IMRPhenomX family of models for gravitational waves from compact binaries: The dominant harmonic for non-precessing quasi-circular black holes

1 code implementation30 Jan 2020 Geraint Pratten, Sascha Husa, Cecilio Garcia-Quiros, Marta Colleoni, Antoni Ramos-Buades, Hector Estelles, Rafel Jaume

In this paper we present IMRPhenomXAS, a thorough overhaul of the IMRPhenomD [1, 2] waveform model, which describes the dominant $l=2, \:| m | = 2$ spherical harmonic mode of non-precessing coalescing black holes in terms of piecewise closed form expressions in the frequency domain.

Gravitational-Wave Asteroseismology with Fundamental Modes from Compact Binary Inspirals

1 code implementation2 May 2019 Geraint Pratten, Patricia Schmidt, Tanja Hinderer

The first detection of gravitational waves (GWs) from the binary neutron star (NS) inspiral GW170817 has opened a unique channel for probing the fundamental properties of matter at supra-nuclear densities inaccessible elsewhere in the Universe.

A simple model of complete precessing black-hole-binary gravitational waveforms

no code implementations14 Aug 2013 Mark Hannam, Patricia Schmidt, Alejandro Bohé, Leila Haegel, Sascha Husa, Frank Ohme, Geraint Pratten, Michael Pürrer

The non-precessing-binary waveforms are then "twisted up" with approximate expressions for the precessional motion, which require only one additional physical parameter, an effective precession spin, $\chi_p$.
