Building an Efficient Cluster Cosmology Software Package for Modeling Cluster Counts and Lensing

Understand

We introduce a software suite developed for galaxy cluster cosmological analysis with the Dark Energy Survey Data.

• Cosmological analyses based on galaxy cluster number counts and weak-lensing measurements need efficient software infrastructure to explore an increasingly large parameter space, and account for various cosmological and astrophysical effects.
• Our software package is designed to model the cluster observables in a wide-field optical survey, including galaxy cluster counts, their averaged weak-lensing masses, or the cluster's averaged weak-lensing radial signals.
• To ensure maximum efficiency, this software package is developed in C++ in the CosmoSIS software framework, making use of the CUBA integration library.
