The One App to Explore the Halo Model and its Predictions.
OnePower is a Python package for computing power spectra and one-point statistics using the halo model framework. It is designed for studying the galaxy-matter connection, cosmological structure formation, and intrinsic alignments, especially in the non-linear regime. This is a Web app access to explore the OnePower.
The OnePower code originated from the merger of the IA halo model repository of Maria-Cristina Fortuna (used in Fortuna et al. 2021) and the halo model code used in Dvornik et al. 2023 and earlier papers. It is designed to natively interact with the CosmoSIS standard library.
