Abstract

Using some of the latest cosmological data sets publicly available, we derive the strongest bounds in the literature on the sum of the three active neutrino masses, ${M}_{\ensuremath{\nu}}$, within the assumption of a background flat $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$ cosmology. In the most conservative scheme, combining Planck cosmic microwave background temperature anisotropies and baryon acoustic oscillations (BAO) data, as well as the up-to-date constraint on the optical depth to reionization ($\ensuremath{\tau}$), the tightest 95% confidence level upper bound we find is ${M}_{\ensuremath{\nu}}<0.151\text{ }\text{ }\mathrm{eV}$. The addition of Planck high-$\ensuremath{\ell}$ polarization data, which, however, might still be contaminated by systematics, further tightens the bound to ${M}_{\ensuremath{\nu}}<0.118\text{ }\text{ }\mathrm{eV}$. A proper model comparison treatment shows that the two aforementioned combinations disfavor the inverted hierarchy at $\ensuremath{\sim}64%\text{ }\text{ }\text{ }\mathrm{C}.\mathrm{L}.$ and $\ensuremath{\sim}71%\text{ }\text{ }\mathrm{C}.\mathrm{L}.$, respectively. In addition, we compare the constraining power of measurements of the full-shape galaxy power spectrum versus the BAO signature, from the BOSS survey. Even though the latest BOSS full-shape measurements cover a larger volume and benefit from smaller error bars compared to previous similar measurements, the analysis method commonly adopted results in their constraining power still being less powerful than that of the extracted BAO signal. Our work uses only cosmological data; imposing the constraint ${M}_{\ensuremath{\nu}}>0.06\text{ }\text{ }\mathrm{eV}$ from oscillations data would raise the quoted upper bounds by $\mathcal{O}(0.1\ensuremath{\sigma})$ and would not affect our conclusions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
