Weighing Neutrinos with Galaxy Surveys

چکیده
We show that galaxy redshift surveys sensitively probe the neutrino mass, with eV mass neutrinos suppressing power by a factor of two. The Sloan Digital Sky Survey can potentially detect N nearly degenerate massive neutrino species with mass mν ∼ 0.65(Ωmh /0.1N) eV at better than 2σ once microwave background experiments measure two other cosmological parameters. Significant overlap exists between this region and that implied by the LSND experiment, and even mν ∼ 0.01− 0.1 eV, as implied by the atmospheric anomaly, can affect cosmological measurements.

Weighing neutrinos with galaxy cluster surveys.
Large future galaxy cluster surveys, combined with cosmic microwave background observations, can achieve a high sensitivity to the masses of cosmologically important neutrinos. We show that a weak lensing selected sample of > or approximately 100,000 clusters could tighten the current upper bound on the sum of masses of neutrino species by an order of magnitude, to a level of 0.03 eV. Since thi...
متن کاملWeighing Neutrinos: Weak Lensing Approach
We study the possibility for a measurement of neutrino mass using weak gravitational lensing. The presence of non-zero mass neutrinos leads to a suppression of power at small scales and reduces the expected weak lensing signal. The measurement of such a suppression in the weak lensing power spectrum allows a direct measurement of the neutrino mass, in contrast to various other experiments which...
متن کاملCurrent cosmological bounds on neutrino masses and relativistic relics
We combine the most recent observations of large-scale structure (2dF and SDSS galaxy surveys) and cosmic microwave anisotropies (WMAP and ACBAR) to put constraints on flat cosmological models where the number of massive neutrinos and of massless relativistic relics are both left arbitrary. We discuss the impact of each dataset and of various priors on our bounds. For the standard case of three...
متن کاملνΛCDM: Neutrinos reconcile Planck with the Local Universe
Current measurements of the low and high redshift Universe are in tension if we restrict ourselves to the standard six parameter model of flat ΛCDM. This tension has two parts. First, the Planck satellite suggests a higher normalization of matter perturbations than local measurements of galaxy clusters. Second, the expansion rate of the Universe today, H0, derived from local distance-redshift m...
متن کاملProbing Neutrino Hierarchy and Chirality via Wakes.
The relic neutrinos are expected to acquire a bulk relative velocity with respect to the dark matter at low redshifts, and neutrino wakes are expected to develop downstream of the dark matter halos. We propose a method of measuring the neutrino mass based on this mechanism. This neutrino wake will cause a dipole distortion of the galaxy-galaxy lensing pattern. This effect could be detected by c...
