Scale covariance and G-varying cosmology. IV. The log N-log s relation
The traditional radio counts N (S) and radio source models are studied within the framework of the scale-covariant 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 t/sup -1/, 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 angular diameter data analysis, favor an open universe.
