Cosmological consequences of a coupling between massive neutrinos and dark energy are investigated. In such models, the neutrino mass is a function of a scalar field, which plays the role of dark energy. The background evolution, as well as the evolution of cosmological perturbations is discussed. We find that mass-varying neutrinos can leave a significant imprint on the anisotropies in the cosmic microwave background radiation and even lead to a reduction of power on large angular scales.

  1. Late-Time Alleviation of the Hubble Tension in CPL Cosmology with Massive Neutrinos via Bayesian Physics-Informed Neural Networks

    astro-ph.CO 2026-01 reject novelty 4.0 of 10

    A Bayesian PINN fit to late-time distance probes finds that CPL dark energy with free neutrino mass shifts H0 to ~70-71.6 km/s/Mpc and lowers the Hubble tension to ~1-2σ, but the tension measure is partly built in by ...

  2. Dark Energy Is Not That Into You: Variable Couplings after DESI DR2 BAO

    astro-ph.CO 2025-08 conditional novelty 4.0 of 10

    With DESI DR2 data, one interacting dark sector model with a time-dependent coupling shows a nonzero coupling at more than 95% CL, but Bayesian evidence still favors Lambda-CDM.
