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…

Astrophysical Implications of Eccentricity in Gravitational Waves from Neutron Star-Black Hole Binaries
Isobel Romero-Shaw, Jakob Stegmann, Gonzalo Morras +2
The gravitational-wave signal from the neutron star-black hole (NSBH) merger GW200105 is consistent with this binary having significant orbital eccentricity close to merger. This r…

Distinguishing the Origin of Eccentric Black Hole Mergers with Gravitational-wave Spin Measurements
Jakob Stegmann, Davide Gerosa, Isobel Romero-Shaw +3
It remains an open question whether the binary black hole mergers observed with gravitational-wave detectors originate from the evolution of isolated massive binary stars or were d…
