Primordial non-Gaussianity — Fast simulations and persistent summary statistics

Check out our new paper: https://arxiv.org/abs/2512.09852 where we introduced the PNG-pmwd Suite —  a collection of 22,410 halo catalogs developed to support data-driven analyses of large-scale structure formation and the impact of primordial non-Gaussianity (PNG). Topological data analysis together with machine learning can unlock new ways to squeeze out early Universe signals beyond traditional n-point statistics:
