Description

CHIMERA (Combined Hierarchical Inference Model for Electromagnetic and gRavitational-wave Analysis) is a flexible Python code to analyze standard sirens with galaxy catalogs, allowing for a joint fitting of the cosmological and astrophysical population parameters within a Hierarchical Bayesian Inference framework.

The code is designed to be accurate for different scenarios, encompassing bright, dark, and spectral sirens methods, and computationally efficient in view of next-generation GW observatories and galaxy surveys. It uses the LAX-backend implementation and Just In Time (JIT) computation capabilities of JAX.

First release; associated to [2312.05302] Cosmology and Astrophysics with Standard Sirens and Galaxy Catalogs in View of Future Gravitational Wave Observations (arxiv.org)
