We study the spherical, top-hat collapse model for a mixed dark matter model including cold dark matter (CDM) and massive neutrinos of mass scales ranging from m_nu= 0.05 to a few 0.1eV, the range of lower- and upper-bounds implied from the neutrino oscillation experiments and the cosmological constraints. To develop this model, we properly take into account relative differences between the density perturbation amplitudes of different components (radiation, baryon, CDM and neutrinos) around the… 
Non-linear evolution of the cosmic neutrino background
We investigate the non-linear evolution of the relic cosmic neutrino background by running large box-size, high resolution N-body simulations which incorporate cold dark matter (CDM) and neutrinos as
MassiveNuS: Cosmological Massive Neutrino Simulations
The non-zero mass of neutrinos suppresses the growth of cosmic structure on small scales. Since the level of suppression depends on the sum of the masses of the three active neutrino species, the
DEMNUni: The clustering of large-scale structures in the presence of massive neutrinos
We analyse the clustering features of Large Scale Structures (LSS) in the presence of massive neutrinos, employing a set of large-volume, high-resolution cosmological N-body simulations, where
Weighing neutrinos with cosmic neutral hydrogen
We investigate the signatures left by massive neutrinos on the spatial distribution of neutral hydrogen (HI) in the post-reionization era by running hydrodynamic simulations that include massive
DEMNUni: Massive neutrinos and the bispectrum of large scale structures
The main effect of massive neutrinos on the large-scale structure consists in a few percent suppression of matter perturbations on all scales below their free-streaming scale. Such effect is of
Semi-analytic galaxy formation in massive neutrino cosmologies
The constraints on neutrino masses led to the revision of their cosmological role, since the existence of a cosmological neutrino background is a clear prediction of the standard cosmological model.
The halo model in a massive neutrino cosmology
We provide a quantitative analysis of the halo model in the context of massive neutrino cosmologies. We discuss all the ingredients necessary to model the non-linear matter and cold dark matter power
Cosmology with massive neutrinos I: towards a realistic modeling of the relation between matter, haloes and galaxies
By using a suite of large box-size N-body simulations that incorporate massive neutrinos as an extra set of particles, we investigate the impact of neutrino masses on the spatial distribution of dark
First Detection of Scale-Dependent Linear Halo Bias in N-Body Simulations with Massive Neutrinos.
TLDR
Using N-body simulations with massive neutrino density perturbations, the scale-dependent linear halo bias is detected with high significance for the first time and is a distinct signature of free-streaming particles and cannot be mimicked by other components of the standard cosmological model.
MASSIVE NEUTRINOS PROMOTE THE SIZE GROWTH OF EARLY-TYPE GALAXIES
The effect of massive neutrinos on the evolution of early-type galaxies in size and stellar mass is explored by tracing the merging history of galaxy progenitors with the help of robust semi-analytic
