Ultralight Bosons Explain the Mass-Spin Correlations in the Merging Binary Black Hole Population

Year: 2026

Type: preprint

Abstract: This archive contains the hierarchical Bayesian population-inference posterior samples underlying the figures and tables of the main body and the End Matter of the paper. Three sets of runs are provided: the superradiance spin model, the delta function spin model, and the Gaussian component spin model baseline against which the Bayes factors of Table I are measured. Each file is a bilby Result object in HDF5 format, produced with dynesty nested sampling via GWPopulation. The superradiant spin-down trajectory chi_SR(M,T_age, m_b) was evaluated with SuperRad.
