Neutrino Mass from Cosmology

Table 1

95% CL upper bounds on the total neutrino mass in eV, for various combinations of CMB, homogeneous cosmology, and LSS data sets. The first seven lines refer to galaxy power spectrum measurements, the next two lines to cluster mass function measurements, the last line to a weak lensing survey. WMAP5 or 7 stands for WMAP 5 or 7-year data. refers to the direct measurement by the HST Key Project [64] and BAO to estimates of the scale of Baryon Acoustic Oscillations at various redshifts. Other acronyms refer to various Large-Scale Structure dataset referred in Section 7.2. In the last column, the cosmological constant was replaced by a Dark Energy component with arbitrary equation-of-state parameter .
