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…
Accounting for numerical-relativity calibration uncertainty in gravitational-wave modeling and inference
Lorenzo Pompili, Alessandra Buonanno, Michael Pürrer
The increasing sensitivity of current and upcoming gravitational-wave (GW) detectors poses stringent requirements on the accuracy of the GW models used for data analysis. If these…
Search for gravitational waves emitted from SN 2023ixf
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1780
We present the results of a search for gravitational-wave transients associated with core-collapse supernova SN 2023ixf, which was observed in the galaxy Messier 101 via optical em…
Real-time gravitational-wave inference for binary neutron stars using machine learning
Maximilian Dax, Stephen R. Green, Jonathan Gair +7
Mergers of binary neutron stars (BNSs) emit signals in both the gravitational-wave (GW) and electromagnetic (EM) spectra. Famously, the 2017 multi-messenger observation of GW170817…
Phenomenology and origin of late-time tails in eccentric binary black hole mergers
Tousif Islam, Guglielmo Faggioli, Gaurav Khanna +3
We investigate the late-time tail behavior in gravitational waves from merging eccentric binary black holes (BBH) using black hole perturbation theory. For simplicity, we focus onl…
