The effect of massive neutrinos on the large scale structure of the Universe

Description
I will present, large scale clustering, weak-lensing, CMB-lensing and ISW/Rees-Sciama photon ray-tracing across the first set of cosmological simulations produced within the “Dark Energy and Massive Neutrino Universe” (DEMNUni) project. These simulations are characterised by Lbox=2Gpc/h, Npart=2 x 20483, a baseline LCDM-Planck cosmology, and four different total neutrino masses, Mnu=0, 0.17, 0.3, 0.53eV, in the form of a particle-component with a degenerate mass spectrum. I will present fully non-linear effects obtained from the DEMNUni simulations, and show how massive neutrinos alter clustering, lensing and ISW/RS together with their cross-correlations
