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…

First eccentric inspiral-merger-ringdown analysis of neutron star-black hole mergers
Maria de Lluc Planas, Sascha Husa, Antoni Ramos-Buades +1
The gravitational wave event GW200105 was the first confident neutron star-black hole (NSBH) merger identified by the LIGO-Virgo-KAGRA collaboration. A recent analysis by Morras et…

Accelerating the time-domain LISA response model with central finite differences and hybridization techniques
Jorge Valencia, Sascha Husa
Accurate and efficient modeling of the Laser Interferometer Space Antenna (LISA) response is crucial for gravitational-wave (GW) data analysis. A key computational challenge lies i…
