SEOBNRv5PHM: Next generation of accurate and efficient multipolar precessing-spin effective-one-body waveforms for binary black holes
Antoni Ramos-Buades, Alessandra Buonanno, Héctor Estellés +5
The paper introduces SEOBNRv5PHM, a fast and accurate effective‑one‑body waveform model that includes multipolar precessing spins for the full inspiral‑merger‑ringdown signal of bi…
Eccentricity constraints disfavor single-single capture in nuclear star clusters as the origin of all LIGO-Virgo-KAGRA binary black holes
Nihar Gupte, M. Coleman Miller, Rhiannon Udall +12
Multiple formation pathways have been proposed for the origin of binary black holes (BBHs). These include isolated binary evolution and dynamical assembly in dense stellar environm…
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…
Accurate waveforms for generic planar-orbit binary black holes: The multipolar effective-one-body model SEOBNRv6EHM
Aldo Gamboa, Alessandra Buonanno, Lorenzo Pompili +8
Accurate and computationally efficient waveform models are required to infer the parameters of compact binaries from their gravitational wave (GW) emission. Among these parameters,…
Merger remnant and eccentricity dynamics surrogates for eccentric nonspinning black hole binaries
Adhrit Ravichandran, Peter James Nee, Keefe Mitman +22
Accurate models of merger remnants are increasingly important for gravitational-wave science, including precision tests of gravity with ringdown, inference of black-hole population…
Evidence for eccentricity in the population of binary black holes observed by LIGO-Virgo-KAGRA
Nihar Gupte, Antoni Ramos-Buades, Alessandra Buonanno +9
Binary black holes (BBHs) in eccentric orbits produce distinct modulations in gravitational waves (GWs); measuring orbital eccentricity provides evidence for dynamical binary forma…
