Abstract

The sky distributions of sources in a RATAN-600 survey and a strip of the 87GB survey have been investigated. The presence of deviations from a Poisson radio source distribution is confirmed. A significant fraction of radio sources are associated with the supercluster-void network, which is composed of regular periodic structures on scales from 30 arcmin to one degree. A comparative study of the distributions and identifications of the RATAN-600 and 87GB surveys is performed. The data from this study are used to set limits on the cosmological parameter qo and the epoch of formation of large scale structures in the Universe.
