This paper proposes extending CosmoDS, a Python toolkit for cosmological model analysis, with linear perturbation theory capabilities to compute CMB power spectra without full Boltzmann solver implementations, aiming to constrain dark energy models using CMB data.
Key findings
CosmoDS will be extended to include linear perturbation theory for CMB power spectrum calculations.
The extension will maintain CosmoDS's computational efficiency and modular structure.
The proposed module will enable direct CMB power spectrum constraints for dark energy models.
Validation protocols against CLASS and CAMB will ensure accuracy.
Limitations & open questions
The paper is a research proposal and does not include implementation results.
The effectiveness of the proposed extension is yet to be validated against existing tools.
