Description
I will present the first set of cosmological simulations produced within
the “Dark Energy and Massive Neutrino Universe” (DEMNUni) project. These
simulations are characterized by L=2 Gpc/h, Npart=2 x 2048^3, a baseline
LCDM-Planck cosmology, and four different total neutrino masses, Mnu=0,
0.17, 0.3, 0.53 eV, with a degenerate mass spectrum. They are the largest
N-body simulations to date with a massive neutrino component treated as an
additional particle type. I will present fully non-linear effects in the
presence of massive neutrinos, extracted from the DEMNUni simulations, and
show how neutrino free-streaming alters not only LSS clustering and
lensing, but introduces also an excess of power in the ISW/RS signals, and
related cross-correlations, at intermediate scales.
