Distinct spin properties and astrophysical origin of low mass binary black holes in gravitational wave data
Elizabeth Flanagan, Jakob Stegmann, Isobel Romero-Shaw +3
We analyze the effective-spin distribution of binary black hole mergers in GWTC-5.0 as a function of primary black hole mass using hierarchical Bayesian inference. We model the pop…
Transitions in the Mass-ratio and Spin Properties of Binary Black Holes in GWTC-5
Elizabeth Flanagan, Fabio Antonini, Thomas Callister +4
We analyze the mass-ratio and effective-spin () distributions of binary black hole mergers in the latest gravitational-wave catalog, GWTC-5, as a function of primary…
Second-Generation Mass Peak in the Gravitational-Wave Population as a Probe of Globular Clusters
Yonadav Barry Ginat, Fabio Antonini, Elizabeth Flanagan +1
Gravitational-wave observations have revealed an excess of binary black hole mergers with primary masses near . We show that if this feature originates from dynam…
Gravitational-wave Observations Suggest Most Black Hole Mergers Form in Triples
Jakob Stegmann, Fabio Antonini, Aleksandra Olejak +4
The spin-orbit tilt angles of merging stellar-mass black holes provide key insights into their astrophysical origin. Non-parametric population modelling of The LIGO, Vi…
