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 m…

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…

Environmental effects in stellar mass gravitational wave sources II: Enhanced detectability of phase shifts in eccentric sub-populations

Lorenz Zwick, Kai Hendriks, Pankaj Saini +4

We demonstrate that the properties of eccentric gravitational wave (GW) signals enhance the detectability of GW phase shifts caused by environmental effects (EEs): The signal-to-no…

Dynamical Evolution of Quasi-Hierarchical Triples

Yonadav Barry Ginat, Jakob Stegmann, Johan Samsing

We study the gravitational dynamics of quasi-hierarchical triple systems, where the outer orbital period is significantly longer than the inner one, but the outer orbit is extremel…

Resolving Black Hole Family Issues Among the Massive Ancestors of Very High-Spin Gravitational-Wave Events Like GW231123

Jakob Stegmann, Aleksandra Olejak, Selma E. de Mink

The latest detection of GW231123, a binary black hole (BH) merger with exceptionally large masses and high spins for the incoming components, has been suggested as a smoking gun fo…

GW200208_222617 as an eccentric black-hole binary merger: properties and astrophysical implications

Isobel Romero-Shaw, Jakob Stegmann, Hiromichi Tagawa +4

Detecting orbital eccentricity in a stellar-mass black-hole merger would point to a non-isolated formation channel. Eccentric binaries can form in dense stellar environments such a…

Dissecting environmental effects with eccentric gravitational wave sources

Lorenz Zwick, Kai Hendriks, David O'Neill +6

We model the effect of resonances between time-varying perturbative forces and the epi-cyclical motion of eccentric binaries in the gravitational wave (GW) driven regime. These ind…
