A comparison of the 1D marginalized posterior distributions for ∑m_ν (eV) across various data combinations. The panel on the right shows results with the DES Year 1 WL included. Note that in the right panel, the Planck PR4+lensing+DESI2+DESY5+WL data set combination leads to a 2σ+ detection of nonzero ∑m_ν. The two vertical black dashed lines (in both panels) indicate the minimum mass thresholds for the normal (0.057 eV) and inverted (0.096 eV) neutrino mass hierarchies, respectively.
