Testing the spin-induced multipole moments of compact binary coalescences using the flexible theory-independent framework

Elise M. Sänger, Alessandra Buonanno, Ajit Kumar Mehta +1

According to the no-hair theorem, the multipole moments of an electrically neutral black hole in general relativity are entirely determined by its mass and spin. However, this is n…

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…

All-sky, all-frequency directional search for persistent gravitational-waves from Advanced LIGO's and Advanced Virgo's first three observing runs

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1627

We present the first results from an all-sky all-frequency (ASAF) search for an anisotropic stochastic gravitational-wave background using the data from the first three observing r…

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…

Efficient Eccentric Effective-One-Body Dynamics via Near-Identity Averaging Transformations

Philip Lynch, Alessandra Buonanno, Aldo Gamboa +1

Next-generation gravitational-wave detectors, such as LISA, the Einstein Telescope, and Cosmic Explorer, will require accurate and efficient models of long-lived black-hole binary…
