Abstract The recent DESI 2024 Baryon Acoustic Oscillations (BAO) measurements combined with the CMB data from the Planck 18 PR3 dataset and the Planck PR4+ACT DR6 lensing data, with a prior on the sum of the neutrino masses ∑ m ν > 0, leads to a strong constraint, ∑ m ν 0 prior. Finally, we analyze neutrino mass bounds in an extension of ΛCDM that addresses the H 0 tension, with extra fluid Dark Radiation, finding that in such models bounds are further relaxed and the posterior probability for ∑ m ν begins to exhibit a peak at positive values.
