Adiabatic tides in compact binaries on quasi-elliptic orbits: Dynamics at the second-and-a-half relative post-Newtonian order
Quentin Henry, Anna Heffernan
GW200105 is the first gravitational wave detection to show signs of eccentricity, it also is a neutron star - blackhole binary. This raises the need for waveforms that incorporate…

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…

What is the nature of GW230529? An exploration of the gravitational lensing hypothesis
Justin Janquart, David Keitel, Rico K. L. Lo +26
On the 29th of May 2023, the LIGO-Virgo-KAGRA Collaboration observed a compact binary coalescence event consistent with a neutron star-black hole merger, though the heavier object…
