Redshift-space distortion constraints on the neutrino mass and models to alleviate the Hubble tension

Understand

We discuss the neutrino mass and Hubble tension solutions and examine their effects on the redshift-space distortion (RSD) observations.

• An analysis with RSD data indicates smaller amplitude of perturbation.
• Including RSD data results in a slightly weaker upper limit on the neutrino mass than that derived for data without RSD, which is common in other extended models too.
• We have evaluated the impacts of RSD observations on some extended models, including the varying electron mass model, a time-dependent dark energy model with two parameter equations of state (EOS), and a model where the number of neutrino species is free.
