| dc.description | Using the initial peculiar velocity field, we analytically study the hierarchical formation of gravitationally bound objects. The field is smoothed over a scale that corresponds to the mass of a given class of objects. Through the Zel'dovich approximation, the smoothed field determines how the objects cluster together to form a new class of more massive objects. The standard cosmological parameters lead to the evolution of primordial clouds with 10^6 M(sun) -> galaxies with 10^12 M(sun) -> clusters of galaxies with 10^15 M(sun) -> superclusters of galaxies with 10^16 M(sun). The epochs obtained for the formation of these classes of objects are consistent with observations. | |
