Simulating cosmologies beyond $Λ$CDM with PINOCCHIO

1 code implementation24 Oct 2016 Luca Alberto Rizzo, Francisco Villaescusa-Navarro, Pierluigi Monaco, Emiliano Munari, Stefano Borgani, Emanuele Castorina, Emiliano Sefusatti

We demonstrate that the abundance of halos in cosmologies with massless and massive neutrinos from PINOCCHIO matches very well the outcome of simulations, and point out that PINOCCHIO can reproduce the $\Omega_\nu-\sigma_8$ degeneracy that affects the halo mass function.

Improving fast generation of halo catalogs with higher-order Lagrangian perturbation theory

1 code implementation16 May 2016 Emiliano Munari, Pierluigi Monaco, Emiliano Sefusatti, Emanuele Castorina, Faizan G. Mohammad, Stefano Anselmi, Stefano Borgani

In Fourier space and using 3LPT for halo displacements, the halo power spectrum is recovered to within 10 per cent up to $k_{max}\sim0. 5\ h/$Mpc.
