Clustering of galaxies in a hierarchical universe -- I. Methods and results at z = 0
Clustering of galaxies in a hierarchical universe -- I. Methods and results at z = 0
We introduce a new technique for following the formation and evolution of galaxies in cosmological N-body simulations. Dissipationless simulations are used to track the formation and merging of dark matter haloes as a function of redshift. Simple prescriptions, taken directly from semi-analytic models of galaxy formation, are adopted for gas …
