Weighing Neutrinos with Galaxy Surveys
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 betwe...
متن کاملDynamic Weighing
In fabricating flowmeters, the meter's calibration is its final and accuracy determining step that comprises a great time consumption relative to its completion from its single component parts. Thus calibration (unless the respective time of calibration for a flow meter is not minimized) may represent a relevant contribution to fabrication costs. High-accuracy liquid flow calibration facilities...
متن کاملWeighing 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 with large-scale structure
While it is established that the effect of neutrinos on the evolution of cosmic structure is small, the upper limits derived from large-scale structure could help significantly to constrain the absolute scale of the neutrino masses. Current results from cosmology set an upper limit on the sum of the neutrino masses of ∼ 1 eV, somewhat depending on the data sets used in the analyses and assumed ...
متن کاملWeighing black holes with warm absorbers
We present a new technique for determining an upper limit for the mass of the black hole in active galactic nuclei showing warm absorption features. The method relies on the balance of radiative and gravitational forces acting on outflowing warm absorber clouds. It has been applied to 6 objects: five Seyfert 1 galaxies: IC 4329a, MCG−6-3015, NGC 3516, NGC 4051 and NGC 5548; and one radio-quiet ...
