Abstract : Over the years various analytical mass function theories like Press-Schechter, Sheth -Tormen have been developed to model the halo mass function. One of the most important characteristics of these theories is that they are independent of cosmological parameters and power spectrum. Various studies over the past two decades, using N-body simulations, have been unable to match the theoretical mass function and in fact, they show a weak dependence on power spectrum and cosmology. We will reinforce this with our suite of simulations ran for scale-free power spectrum in EdS cosmology. Selecting such conditions is advantageous due to self-similar evolution.
