Citing ξ Dark Energy

ξ Dark Energy is an exploratory cosmology project comparing ΛCDM, CPL, and an oscillatory dark-energy extension using Type Ia supernovae and BAO measurements.

Current status

This project is exploratory and should not be cited as evidence for a new cosmological model. It can be cited as a research-code and methodology project, especially for portfolio, documentation, and reproducibility purposes.

How to describe the project

Recommended wording:

ξ Dark Energy is an exploratory cosmology pipeline that compares ΛCDM, CPL, and an oscillatory dark-energy parameterization using Pantheon+SH0ES supernovae and DESI DR2 BAO data. The project emphasizes reproducible MCMC inference, diagnostic transparency, and explicit caveats.

Avoid wording that implies discovery or confirmation of oscillatory dark energy.

What to cite for each use case

Use case	Recommended citation
General project reference	Provisional ξ Dark Energy citation
Data-likelihood implementation	Provisional citation + Likelihood page
MCMC setup	Provisional citation + MCMC Setup page
Priors	Provisional citation + Prior Specification page
Parameter constraints	Provisional citation + Parameter Constraints page
Caveats and limitations	Provisional citation + Known Limitations page
Future tagged release	Replace with Zenodo DOI once available

Citation caveats

The current analysis should always be cited with the following qualifiers:

• the model is phenomenological,
• the result is exploratory,
• convergence diagnostics must be inspected,
• prior sensitivity is not yet fully closed,
• the v0.2 roadmap includes corrections and robustness checks,
• the project should not be presented as evidence for a departure from ΛCDM without further validation.

caution

Do not cite ξ-model parameter constraints without also citing the caveats page. In this project, the limitations are part of the scientific interpretation.
