Image Details
Caption: Figure 11.
This figure illustrates the robustness of the preference for positive neutrino masses to other parameter extensions. The marginalized
one-dimensional posteriors for ∑
m
ν are shown for two-parameter extensions to ΛCDM for the combined CMB+BAO+
H
0+
data sets (for
w, SNe are used instead of
H
0). Allowing significant curvature or running can significantly reduce the preference for nonzero neutrino masses (to 1.7 and
2.4σ respectively). Other extensions increase the preference for positive neutrino masses.
