Figure 38: DM halo mass function (MF) as a function of Σ and redshift. MF of the SUBFIND haloes in the ΛCDM N-body simulation (blue circles) and in the two simulations with Σ = 0.3 eV (magenta triangles) and Σ = 0.6 eV (red squares). The blue, magenta and red lines show the halo MF predicted by [824], where the variance in the density fluctuation field, σ(M ), at the three cosmologies, Σ = 0,0.3,0.6 eV, has been computed with the software camb [559].
