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…
GWTC-5.0: Population Properties of Merging Compact Binaries
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1813
We present the population properties of merging compact binaries inferred using 267 mergers from the cumulative Gravitational-Wave Transient Catalog 5.0. As this data set contains…
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…
cBHBd: A fast code for the evolution of tidally limited star clusters and their binary black hole mergers
Fotios Fronimos Pouliasis, Nolan Dickson, Daniel MarÃn Pina +3
The evolution of star clusters is driven by stellar mass loss, two-body relaxation, and evaporation in the Galactic tidal field. Fast modeling tools are crucial for exploring diver…
Gravitational-wave constraints on the pair-instability mass gap and nuclear burning in massive stars
Fabio Antonini, Isobel Romero-Shaw, Thomas Callister +5
Pair-instability should prevent the direct formation of black holes above about creating a pair-instability mass gap. Yet gravitational-wave observations have detected…
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…
