Analyses of the growing catalog of binary black hole (BBH) mergers observed by the LIGO-Virgo-KAGRA detectors are beginning to resolve features in their population-level mass, spin…
The LISA Astrophysics MBHcatalogues Project: A comparison of predictions of simulated massive black hole binaries
David Izquierdo-Villalba, Melanie Habouzit, Matteo Bonetti +67
In the hierarchical paradigm of galaxy formation, central massive black holes (MBHs) are expected to coalesce after the merger of their host galaxies. One of the main goals of the…
Eccentricity constraints disfavor single-single capture in nuclear star clusters as the origin of all LIGO-Virgo-KAGRA binary black holes
Nihar Gupte, M. Coleman Miller, Rhiannon Udall +12
Multiple formation pathways have been proposed for the origin of binary black holes (BBHs). These include isolated binary evolution and dynamical assembly in dense stellar environm…
Inferring the population properties of galactic binaries from LISA's stochastic foreground
Federico De Santi, Alessandro Santini, Alexandre Toubiana +2
Galactic binaries are expected to be the most numerous LISA sources and to produce a stochastic gravitational-wave foreground whose spectral shape encodes information about the und…
