Fast gravitational waveform models for quasi-circular coalescences of neutron star--black hole binaries
Felip A. Ramis Vidal, Adrian Abac, Marta Colleoni +5
We present IMRPhenomXHM_NSBH and SEOBNRv5HM_ROM_NRTidalv3_NSBH, the first two frequency-domain models for gravitational-wave signals from quasi-circular, aligned-spin neutron star-…
Remnant recoil and host environments of GWTC-4.0 binary black-hole mergers
Joan Llobera-Querol, Eleanor Hamilton, Neha Singh +8
Determining the astrophysical origin of binary black holes and whether merger remnants are retained in their birth environments is essential for understanding hierarchical mergers…
Parameter estimation for the GWTC-4.0 catalog with phenomenological waveform models that include orbital eccentricity and an updated description of spin precession
Yumeng Xu, Jorge Valencia, Héctor Estellés Estrella +11
The GWTC-4.0 catalog of transient gravitational wave signals describes observations made in the first part of the fourth observing run of the LIGO-Virgo-KAGRA (LVK) gravitational w…
Leveraging NRTidalv3 to develop gravitational waveform models with higher-order modes for binary neutron star systems
Adrian Abac, Felip A. Ramis Vidal, Marta Colleoni +3
Accurate and reliable gravitational waveform models are crucial in determining the properties of compact binary mergers. In particular, next-generation gravitational-wave detectors…
PhenomXPNR: An improved gravitational wave model linking precessing inspirals and NR-calibrated merger-ringdown
Eleanor Hamilton, Marta Colleoni, Jonathan E. Thompson +10
We present the frequency-domain quasi-circular precessing binary-black-hole model PhenomXPNR. This model combines the most precise available post-Newtonian description of the evolu…
