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…
Third post-Newtonian dynamics for eccentric orbits and aligned spins in the effective-one-body waveform model SEOBNRv5EHM
Aldo Gamboa, Mohammed Khalil, Alessandra Buonanno
Accurate waveform models for coalescing binaries on eccentric orbits are crucial for avoiding biases in the analysis of eccentric gravitational-wave signals. The effective-one-body…
Accurate waveforms for eccentric, aligned-spin binary black holes: The multipolar effective-one-body model SEOBNRv5EHM
Aldo Gamboa, Alessandra Buonanno, Raffi Enficiaud +9
The measurement of orbital eccentricity in gravitational-wave (GW) signals will provide unique insights into the astrophysical origin of binary systems, while ignoring eccentricity…
Testing eccentric corrections to the radiation-reaction force in the test-mass limit of effective-one-body models
Guglielmo Faggioli, Maarten van de Meent, Alessandra Buonanno +3
In this work, we test an effective-one-body radiation-reaction force for eccentric planar orbits of a test mass in a Kerr background, which contains third-order post-Newtonian (PN)…
Post-Newtonian observables for aligned-spin binaries to sixth order in spin from gravitational self-force and Compton amplitudes
Yilber Fabian Bautista, Mohammed Khalil, Matteo Sergola +2
Accurate modeling of compact binaries is essential for gravitational-wave detection and parameter estimation, with spin being an important effect to include in waveform models. In…
