| Abstract: |
Using high resolution N -body simulations we study the formation and evolution of clusters and groups in a &Lambda CDM cosmological model. Groups of galaxies already form before z = 4. Merging of groups and accretion leads to cluster formation at z <&sim2. Some of the groups merge into large isolated halos. |
