Molino Galaxy Catalogs — 75,000 mock galaxy catalogs, constructed from full N-body simulations, designed to quantify the information content of any cosmological observable for a redshift-space galaxy sample.

Quijote Simulations — >43,000 full N-body simulations designed to quantify the information content of cosmological observables and train machine learning algorithms. Over a petabyte of data publicly available!

pySpectrum — Python package for measuring the power spectrum and bispectrum using the Scoccimarro (2015) estimator.

LetsTalkAboutQuench — Identify the star-forming sequence of galaxies using Gaussian mixture models and Bayesian Information Criteria in a data-driven approach. See Hahn et al. (2019) for details.
