Clustering in Massive Neutrino Cosmologies via Eulerian Perturbation Theory

Understand

We introduce an Eulerian Perturbation Theory to study the clustering of tracers for cosmologies in the presence of massive neutrinos.

• Our approach is based on mapping recently-obtained Lagrangian Perturbation Theory results to the Eulerian framework.
• We add Effective Field Theory counterterms, IR-resummations and a biasing scheme to compute the one-loop redshift-space power spectrum.
• To assess our predictions, we compare the power spectrum multipoles against synthetic halo catalogues from the Quijote simulations, finding excellent agreement on scales $k\lesssim 0.25 \,h \text{Mpc}^{-1}$.
