firecrown

Firecrown: A framework for cosmological likelihood analysis.

Firecrown provides a framework for implementing cosmological likelihoods and connecting them to external statistical analysis tools. It is developed by the LSST Dark Energy Science Collaboration (DESC).

Key Features:

• Flexible likelihood framework for various cosmological observables

• Integration with CCL (Core Cosmology Library) for theoretical predictions

• Support for two-point statistics, cluster abundance, weak lensing, and supernova distance moduli

• Connector interfaces for samplers (e.g., CosmoSIS, NumCosmo, Cobaya)

• Updatable parameter system for efficient likelihood evaluation

Main Submodules:

• likelihood: Likelihood implementations and infrastructure

• models: Theoretical models for cosmological observables

• modeling_tools: Cosmological modeling utilities (CCL integration)

• parameters: Parameter management system

• connector: Interfaces to external sampling frameworks

• updatable: Base classes for parameter updates
