Banerjee, S.K.Narlikar, J.V.2015-03-012015-03-012015-03-01http://hdl.handle.net/11007/2918The data on angular sizes and redshifts of ultracompact radio sources used by Jackson and Dodgson in a recent paper have been applied to the various theoretical models in the framework of the quasi-steady state cosmology proposed by Hoyle, Burbidge and Narlikar. It is found that although acceptable fits to the data are available for the fiat models, those with a negative curvature of spatial sections provide a better fit. These latter models require low densities of matter and as such do not demand too high a proportion of dark matter. A comparison is made with the work of Jackson and Dodgson and theoretical implications of the test are discussed.enCosmologyArticle
