Abstract

We use cosmological hydrodynamic simulations to model galaxy formation at redshift 5 and higher. We explore how galaxies populate dark matter halos, focusing on the implications for the clustering properties of galaxies in the context of current and future deep surveys. We find a significant trend for galaxies with high gas fractions to lie in denser environments than gas poor galaxies of the same halo mass, as reflected by their different clustering strengths.
