Cumulative halo mass function
Web1 day ago · Limits on the abundance of galaxies as a function of redshift Curves show the relationship between M⋆ and z at fixed cumulative halo abundance (left) and fixed ρb (>Mhalo), or equivalently ... WebMay 18, 2024 · 4.1 Halo mass function. One of the most basic quantities predicted by simulations is the halo mass function. The cumulative halo mass function (HMF) N(>M) defines the number of haloes above a certain mass M per comoving volume. In AW10, the number densities were properly matched with a bias of order ≲10 per cent.
