Reversible-jump MCMC reveals binary black hole subpopulations with distinct redshift evolution
April Qiu Cheng, Alexandre Toubiana, Sylvia Biscoveanu +1
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…
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…
Probing the redshift evolution and sub-populations of binary neutron stars with the Einstein Telescope
Alexandre Toubiana, Irina Dvorkin
The formation channels of binary neutron stars (BNSs) currently remain uncertain, but important information can be gathered by observing their mergers with gravitational-wave detec…
Where did Heavy Binaries Go? Gravitational-wave Populations Using Delaunay Triangulation with Optimized Complexity
Rodrigo Tenorio, Alexandre Toubiana, Tristan Bruel +2
We investigate the joint mass-redshift evolution of the binary black-hole merger rate in the latest Gravitational-Wave Transient Catalog, GWTC-4.0. We present and apply a novel non…
Reconstructing parametric gravitational-wave population fits from non-parametric results without refitting the data
Cecilia Maria Fabbri, Davide Gerosa, Alessandro Santini +3
Combining multiple events into population analyses is a cornerstone of gravitational-wave astronomy. A critical component of such studies is the assumed population model, which can…
Detectable environmental effects in GW190521-like black-hole binaries with LISA
Alexandre Toubiana, Laura Sberna, Andrea Caputo +9
GW190521 is the compact binary with the largest masses observed to date, with at least one in the pair-instability gap. This event has also been claimed to be associated with an op…
Gravitational-wave detection and parameter estimation for accreting black-hole binaries and their electromagnetic counterpart
Andrea Caputo, Laura Sberna, Alexandre Toubiana +4
We study the impact of gas accretion on the orbital evolution of black-hole binaries initially at large separation in the band of the planned Laser Interferometer Space Antenna (LI…
