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…

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, Vir…

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…

Imprints of massive black-hole binaries on neighbouring decihertz gravitational-wave sources

Jakob Stegmann, Lorenz Zwick, Sander M. Vermeulen +2

The most massive black holes in our Universe form binaries at the centre of merging galaxies. The recent evidence for a gravitational-wave (GW) background from pulsar timing may co…

Double black hole mergers in nuclear star clusters: eccentricities, spins, masses, and the growth of massive seeds

Debatri Chattopadhyay, Jakob Stegmann, Fabio Antonini +2

We investigate the formation of intermediate mass black holes (IMBHs) through hierarchical mergers of stellar origin black holes (BHs), as well as BH mergers formed dynamically in…

Flipping spins in mass transferring binaries and origin of spin-orbit misalignment in binary black holes

Jakob Stegmann, Fabio Antonini

Close stellar binaries are prone to undergo a phase of stable mass transfer in which a star loses mass to its companion. Assuming that the donor star loses mass along the instantan…
