End-to-End Population Inference from Gravitational-Wave Strain using Transformers
Konstantin Leyde, Stephen R. Green, Maximilian Dax +3
The population of compact binaries encodes information about their astrophysical origins and the expansion of the universe. Hierarchical Bayesian methods infer these properties by…

Variance of gravitational-wave populations
Alessia Corelli, Davide Gerosa, Matthew Mould +1
We quantify the impact of finite catalog size, or "catalog variance," on current gravitational-wave population analyses. The distribution of merging binary black holes is commonly…

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…
