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…
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…
Biased parameter inference of eccentric, spin-precessing binary black holes
Divyajyoti, Isobel M. Romero-Shaw, Vaishak Prasad +8
While the majority of gravitational wave (GW) events observed by the LIGO and Virgo detectors are consistent with mergers of binary black holes (BBHs) on quasi-circular orbits, som…
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…
The Early Career Workshop of GR-Amaldi 2025
S Al-Shammari, C P L Berry, C E A Chapman-Bird +18
Gravitational physics and astronomy have developed rapidly over the last decade, driven by new observations and theoretical breakthroughs. As new as the science and technology of t…
