We use a semianalytical approach, and the standard σ8 = 1 cold dark matter (SCDM) cosmological model to study the gravitational collapse and virialization, the structure, as well as the global and statistical properties of isolated dark matter (DM) galactic halos which emerge from primordial Gaussian fluctuations. Firstly, from the statistical properties of the primordial density fluctuation field the possible mass aggregation histories (MAHs) are generated. Secondly, these histories are used… CONTINUE READING
