Biased Tracers in Redshift Space in the EFTofLSS with exact time dependence

Understand

We study the effect of the Einstein - de Sitter (EdS) approximation on the one-loop power spectrum of galaxies in redshift space in the Effective Field Theory of Large-Scale Structure.

• The dark matter density perturbations and velocity divergence are treated with exact time dependence.
• Splitting the density perturbation into its different temporal evolutions naturally gives rise to an irreducible basis of biases.
• While, as in the EdS approximation, at each time this basis spans a seven-dimensional space, this space is a slightly different one, and the difference is captured by a single calculable time- and $\vec k$-dependent function.
