Do black-hole population models fit to O3-era LIGO data predict the 2025-26 catalogs?
An out-of-sample test of black-hole population models: fit to O3-era LIGO gravitational-wave data, then scored against the newest public O4a and O4b catalogs.
Two-epoch pre-registration: O4a then O4b
Fully public LIGO gravitational-wave catalogs
Tests whether current population models actually generalize
