Parity symmetry as a diagnostic for spin-precessing binary-black-hole waveform models
Héctor Estellés, Sascha Husa, Eleanor Hamilton +3
Parity invariance of general relativity imposes exact relations between waveforms and remnant properties of binary-black-hole configurations related by reversal of the in-plane spi…
Identifying galactic binary systems of neutron stars and black holes with LISA
Hannah Middleton, Panagiota Kolitsidou, Antoine Klein +3
The Laser Interferometer Space Antenna (LISA) will detect galactic binary systems comprised of black holes and neutron stars. Distinguishing these binaries from the $\si…
Impact of anti-symmetric contributions to signal multipoles in the measurement of black-hole spins
Panagiota Kolitsidou, Jonathan E. Thompson, Mark Hannam
Many current models for the gravitational-wave signal from precessing black-hole binaries neglect an asymmetry in the multipoles. The asymmetry is weak, but is responsible…
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…
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…
