"The Halo-Void Model of Large Scale Structure"

The Halo Model (HM) of Large Scale Structure has enriched our comprehension of how matter is distributed in the Universe. Through the assumption that all matter particles are inside dark matter halos, a natural consequence is that statistical properties of dark matter split into two contributions: one that comes from correlations inside each halo and another coming from correlations across matter particles of different halos. In this work, we extend this assumption by allowing the matter to rest not only inside halos but also inside voids (HVM). We show that including voids into the calculations significantly improves the HM prediction for the dark matter power spectrum, which demonstrates that halos and voids are complementary structures of the Universe. The HVM solves typical practical problems of the HM, such as the need for integrating the mass function down to very small halo masses. Within the HVM we can also provide predictions for cross-correlation functions (e.g. halo-matter and void-matter), as well as the density profiles, with a natural computation of convergent large scale contributions.
