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…
Enhancing the SEOBNRv5 effective-one-body waveform model with second-order gravitational self-force fluxes
Maarten van de Meent, Alessandra Buonanno, Deyan P. Mihaylov +7
The paper incorporates second‑order gravitational self‑force calculations into the SEOBNRv5 effective‑one‑body waveform model, improving its mode amplitudes, energy flux, and bindi…
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…
Joint inference of line-of-sight acceleration and orbital eccentricity in neutron-star--black-hole binaries
Lorenzo Pompili, Aldo Gamboa, Alessandra Buonanno
A line-of-sight acceleration (LOSA) of a compact-binary center of mass, imparted for example by a nearby tertiary perturber, imprints a Doppler modulation on the gravitational-wave…
Eccentric and unbound compact binaries in the LIGO-Virgo-KAGRA catalog: parameter estimation and waveform systematics with SEOBNRv6EHM
Lorenzo Pompili, Aldo Gamboa, Alessandra Buonanno
Orbital eccentricity encodes key information about compact-binary formation channels and astrophysical environments, making it a critical target for gravitational-wave (GW) inferen…
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,…
