Scale covariance and Gvarying cosmology. IV. The logNlogS relation.
Abstract
The traditional radio counts N(S) and radio source models are studied within the framework of the scalecovariant cosmology developed to investigate whether the relative strength of the gravitational and electromagnetic constants is a function of cosmological epoch. It is found that a gravitational constant G varying as the inverse of t, where t is the epoch in atomic units, is consistent with all the data analyzed. For a wide class of models the present cosmology allows a finer discrimination of the deceleration parameter than does standard theory. The results, when combined with those of previous papers, namely, those from radio and optical flux and angulardiameter data analysis, favor an open universe.
