Title: Probing neutrino masses with WFMOS using nonlinear galaxy power spectrum in redshift-space
Authors: Shun Saito, Masahiro Takada, Atsushi Taruya
Abstract:  The wide and deep galaxy surveys such as WFMOS will provide us great opportunities to probe 
the neutrino masses as long as dark energy parameters. This is due to the fact that massive neutrinos 
suppress the matter power spectrum at the scales larger than neutrino free-streaming scale which 
roughly corresponds to baryon acoustic scillations (BAOs). In this talk we address nonlinear effects 
on galaxy power spectrum, i.e. nonlinearity of gravitational evolution, galaxy biasing and redshift 
distortions. Modeling the nonlinear galaxy power spectrum with massive neutrinos, we present expected 
constraints on neutrino masses with WFMOS. Moreover, we argue the degeneracies among neutrino masses 
and other cosmological parameters such as dark energy parameter.
