Description
The latest generation of large-scale structure surveys requires computational frameworks that are not only accurate, but also modular, reproducible, fast and sustainable in time. We present cloe-org, a new computational environment for LSS cosmology, built around the development of CLOE: the Cosmology Likelihood for Observables in Euclid. Designed to support end-to-end cosmological analyses, cloe-org brings together theoretical modelling, likelihood evaluation, inference tools, validation workflows, and collaborative software practices within a unified ecosystem. Its current applications span spectroscopic galaxy cluster, and weak lensing, photometric clustering, galaxy-galaxy lensing, and their combinations, while allowing for the inclusion of key astrophysical and observational systematics and some cross-correlation with CMB. By providing a flexible environment for testing modelling choices, priors, scale cuts, and extended cosmological scenarios, cloe-org aims to make precision LSS analyses more transparent, efficient, and robust. This framework is developed with Euclid in mind, but with the broader goal of serving the cosmology community in the era of high-dimensional, survey-scale inference.
