The accuracy of state-of-the-art cosmological measurements allows us to obtain information about the mass of neutrinos. The new limits to this mass established using recent galaxy surveys are very interesting, in particular for the consequences for particle physics. They reveal that we might be near the discovery of the neutrino mass hierarchy and/or the measure of the mass of these enigmatic particles.

Researchers Antonio J. Cuesta and Licia Verde, from the Institute of Cosmos Sciences (IEEC-UB), and Viviana Niro, researcher from the Universidad Autónoma de Madrid, have recently published an academic work about neutrinos using the Universe as a huge detector. In this work they present cosmological upper limits on the sum of active neutrino masses using large-scale power spectrum data from the WiggleZ Dark Energy Survey and from the Sloan Digital Sky Survey - Data Release 7 sample of Luminous Red Galaxies.
