The UniverseMachine is a self-consistent empirical model of galaxy formation in dark matter halos. It is constrained via observed galaxy stellar mass functions, star formation rates, clustering, luminosity functions, and quenched fractions. This dataset includes derived constraints on galaxy-halo relationships, star formation histories, merger histories, and predicted observables. Full mock catalogs with galaxy properties are available here. For inquiries regarding the contents of this dataset, please contact the Corresponding Author listed in the README.txt file. Administrative inquiries (e.g., removal requests, trouble downloading, etc.) can be directed to data-management@arizona.edu
