The inferred parameters from PE are red-shifted. If we want the source-frame parameter, we may need to add cosmological models. For bilby, they use astropy.cosmology.FlatLambdaCDM but it is not written in jax. We may need one that is written in jax. https://docs.astropy.org/en/stable/api/astropy.cosmology.FlatLambdaCDM.html#astropy.cosmology.FlatLambdaCDM

https://wcosmo.readthedocs.io/en/latest/ is a (mostly-stable) jax port of some astropy cosmologies
