New code release from NEDE-Cosmo!
We have made public the likelihood code for our work on Dark Acoustic Oscillations (DAOs) and the interpretation of DESI DR2:
DAO_bias_DESI_DR2:
https://github.com/NEDE-Cosmo/DAO_bias_DESI_DR2
The repository provides a Cobaya likelihood implementing the DAO bias effect studied in our paper (arXiv:2512.15870), making it straightforward to explore this effect in cosmological parameter analyses.
It is part of our NEDE-Cosmo GitHub page, where we are collecting codes and likelihoods developed in connection with our work on cosmic tensions and physics beyond ΛCDM:
This already includes TriggerCLASS for Cold New Early Dark Energy (Cold NEDE), DRMD-CLASS for Dark Radiation–Matter Decoupling / Hot NEDE, and now the DESI DR2 DAO-bias likelihood.
