摘要: A cosmological model in which the primordial perturbations are provided by global monopoles and dark matter is cold has several interesting features. The normalized choosing its single parameter within bounds obtained from gravitational wave constraints demanding coherent velocity flows of about 600 km/sec on scales 50h-1Mpc. Using this normalization, predicts existence dominant structures with mass 2×1016M⊙ a scale 35h-1Mpc, i.e., larger than horizon at tep. magnitude predicted function galactic range good agreement observed Schechter function.
