PhenomXO4a: a phenomenological gravitational-wave model for precessing black-hole binaries with higher multipoles and asymmetries
Jonathan E. Thompson, Eleanor Hamilton, Lionel London +4
In this work we introduce PhenomXO4a, the first phenomenological, frequency-domain gravitational waveform model to incorporate multipole asymmetries and precession angles tuned to…
Revisiting the cosmic string origin of GW190521
Josu C. Aurrekoetxea, Charlie Hoy, Mark Hannam
For the first time we analyse gravitational-wave strain data using waveforms constructed from strong gravity simulations of cosmic string loops collapsing to Schwarzschild black ho…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
First frequency-domain phenomenological model of the multipole asymmetry in gravitational-wave signals from binary-black-hole coalescence
Shrobana Ghosh, Panagiota Kolitsidou, Mark Hannam
Gravitational-wave signals from binaries that contain spinning black holes in general include an asymmetry between the and multipoles that is not included in most signal…
A catalogue of precessing black-hole-binary numerical-relativity simulations
Eleanor Hamilton, Edward Fauchon-Jones, Mark Hannam +9
We present a public catalogue of numerical-relativity binary-black-hole simulations. The catalogue contains datasets from 80 distinct configurations of precessing binary-black-hole…
Ringdown frequencies in black holes formed from precessing black-hole binaries
Eleanor Hamilton, Lionel London, Mark Hannam
We present a simple formula for the effective ringdown frequencies of the gravitational-wave signal of a precessing black-hole binary in the co-precessing frame. This formula requi…
