A stepping stone toward detecting gravitational wave memory: a cumulative analysis with the full spherical harmonic using events from GWTC-4.0 and GWTC-5.0
Maria Rosselló-Sastre, Sascha Husa, Yumeng Xu +3
We perform Bayesian model selection to test for the presence of the spherical harmonic mode in gravitational wave events that have previously been identified as bina…

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…

Hybrid waveforms for precessing quasi-circular binary systems
Joan Llobera-Querol, Sascha Husa, Maria de Lluc Planas
The demand for long and accurate gravitational waveforms is increasing as we prepare for the next generation of detectors and seek to improve current waveform models. However, nume…
