摘要:
我们介绍了CosmoDS工具包,旨在利用Cobaya框架内的动态系统分析来研究宇宙模型的背景层面。动态系统分析是一种强大的数学方法,用于研究非线性系统,广泛应用于宇宙学中研究不同宇宙模型的稳定性与演化,尤其是涉及暗能量的模型。在该代码中,我们提供了一个基于动态系统方法的框架,用于约束宇宙模型。最重要的是,该工具包直接集成到Cobaya接口中,使用户能够利用Cobaya中已实现的高级统计和推断工具,用于宇宙学参数估计和模型分析。
英文摘要:
We present a toolkit, CosmoDS, designed to study cosmological models at the background level using dynamical system analysis within the Cobaya framework. Dynamical system analysis is a powerful mathematical approach for studying nonlinear systems and is widely used in cosmology to investigate the stability and evolution of different cosmological models, particularly those involving dark energy. In this code, we provide a framework for constraining cosmological models using a dynamical system formulation. Most importantly, the toolkit is directly integrated with the Cobaya interface, allowing users to take advantage of the sophisticated statistical and inference tools already implemented in Cobaya for cosmological parameter estimation and model analysis.
