+title: "Effort.jl: a fast and differentiable emulator for the Effective Field Theory of the Large Scale Structure of the Universe"
+id: "marcobonici-effort"
+description: "See how this team uses Julia to emulate cosmological observables at the largest scales."
+author: "[William Thompson](https://github.com/sefffal)"
+date: "2025-09-16"
+---
+
+This team has developed a novel and efficient emulator designed for the Effective Field Theory of Large-Scale Structure (EFTofLSS).
+
+**Package: [CosmologicalEmulators/Effort.jl](https://github.com/sefffal/Octofitter.jl)**
+
+![image](https://raw.githubusercontent.com/CosmologicalEmulators/Effort.jl/refs/heads/main/docs/src/assets/logo.svg)
+
+Their implementation leverages state-of-the-art numerical methods and machine learning techniques from the [SciML](https://sciml.ai/) and [Turing.jl](https://turinglang.org/) ecosystems to create surrogate models of the large-scale structure of the Universe. These models integrate well with gradient-based samplers to achieve exceptional computational performance without sacrificing accuracy, which will be essential for analyzing next-generation cosmological survey data from, e.g., the Dark Energy Spectroscopic Instrument ([DESI](https://www.desi.lbl.gov/)), and [Euclid](https://www.esa.int/Science_Exploration/Space_Science/Euclid).

+Read the [_404 Media_ news release](https://www.404media.co/a-vast-cosmic-web-connects-the-universe-really-now-we-can-emulate-it/) on this package, or read from an up-to-date list of associated publications from the [CosmologicalEmulators organization here](https://github.com/CosmologicalEmulators#publications) for more.
