Revealing Four Subpopulations of Binary Black-Hole Mergers with the Fifth Gravitational-Wave Transient Catalog
Nir Guttman, Paul D. Lasky, Eric Thrane
Gravitational-wave data are beginning to reveal a structured landscape of black-hole masses and spins, suggesting multiple formation processes are now being resolved observationall…
Joint inference for gravitational-wave signal and noise glitch: Method and application
Shun Yin Cheung, Rhiannon Udall, Derek Davis +2
Non-Gaussian noise transients ("glitches") in gravitational-wave observatories degrade our ability to accurately perform astrophysical inference. We present the analysis pipeline b…
Fortifying gravitational-wave population inference with normalizing flows
Christian Adamcewicz, Hugh McDougall, Paul D. Lasky +1
As the LIGO-Virgo-KAGRA collaboration's (LVK's) gravitational-wave transient catalog grows, we are learning a wealth of information from the population properties of binary black h…
Licence to Bin: Accurate and Scalable Inference for Binary Neutron Stars in Next-Generation Gravitational-Wave Detectors
Nir Guttman, A. Makai Baker, Paul D. Lasky +1
Next-generation gravitational-wave observatories will observe binary neutron-star mergers with much higher signal-to-noise ratios, over much longer durations and across broader fre…
Evidence for Three Subpopulations of Merging Binary Black Holes at Different Primary Masses
Sharan Banagiri, Eric Thrane, Paul D. Lasky
With the release of the fourth LIGO--Virgo--KAGRA gravitational-wave catalog (GWTC-4), we are starting to gain a detailed view of the population of merging binary black holes. The…
A universal framework to identify eccentric binary mergers: GW200105 case study
Teagan A. Clarke, Isobel M. Romero-Shaw, Charlie Hoy +3
Orbital eccentricity in gravitational-wave signals from merging compact object binaries is a powerful indicator of their formation channel. Several binary black hole mergers and a…
