Euclid Level-0 Science Requirements Sector Euclid Targets Measure the cosmic expansion history to better than 10% in redshift bins 0.7 < z < 2 . • Look for deviations from w = − 1, indicating a dynamical dark energy. • Dark Energy Euclid alone to give FoM DE > 400 ( 1-sigma errors on w p , & w a of 0.02 and 0.1 respectively) • Measure the growth index, γ , with a precision better than 0.02 • Measure the growth rate to better than 0.05 in redshift bins between 0.5< z < 2. • Test Gravity Separately constrain the two relativistic potentials Ψ , Φ . • Test the cosmological principle • Detect dark matter halos on a mass scale between 10 8 and >10 15 M Sun • Measure the dark matter mass profiles on cluster and galactic scales • Dark Matter Measure the sum of neutrino masses, the number of neutrino species and the neutrino • hierarchy with an accuracy of a few hundredths of an eV Measure the matter power spectrum on a large range of scales in order to extract values for • the parameters σ 8 and n to a 1-sigma accuracy of 0.01. Initial For extended models, improve constraints on n and α wrt to Planck alone by a factor 2. • Conditions Measure a non-Gaussianity parameter f NL for local-type models with an error less than +/-2. • • DE equation of state: P/ ρ = w , and w(a) = w p + w a (a p -a) • Growth rate of structure formation: f ~ Ω γ ; FoM=1/( Δ w a x Δ w p ) > 400 à ~1% precision on w’s . • Meeting Euclid France APC, 07-08 Jan 2016
