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…

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…

Waveform model for the spherical harmonic and the displacement memory contribution from precessing binary black holes
Maria Rosselló-Sastre, Sascha Husa
In this paper we construct the first phenomenological waveform model which contains the "complete" spherical harmonic mode content for gravitational wave signals emitted b…
