The centers of large-scale nonhomogeneities of quasar distribution in the universe
Abstract
Statistical investigations of a quasar catalog containing more than 7000 objects are presented.It is shown that quasars in quasar-galaxy associations (quasars of associations) have the same peculiarities of space distribution as quasars with absorptions.In the standard Friedman cosmological model the quasars of associations (and quasars with absorptions) are the centers of large-scale (1000 Mpc and more) nonhomogeneities in space distribution of qasars.The nonhomogeneities are some deficit of quasars around quasars of associations.Density of quasars around these centers is 2.5 times less than their density around quasars without absorptions.
