News • News • Dec. 13, 2024, 7:16 AM ET (Astronomy Magazine) Big bang cosmology, augmented by the ideas of inflation, remains the theory of choice among nearly all astronomers, but, apart from the difficulties discussed above, no consensus has been reached concerning the origin in ...
We also discuss our 'filtered' 6C redshift surveys: these have led to the discovery of a radio galaxy at z = 4.4, and are sensitive to similar objects at higher redshift provided the space density of these objects, p, is not declining too rapidly with z. There is currently no direct ...

3C. To improve on this situation we have been undertaking redshift surveys of complete samples drawn from the fainter 6C and 7C radio catalogues. We describe these surveys, and illustrate the new studies they are allowing. We also discuss our `filtered' 6C redshift surveys: these have led ...
In a series of articles, we have shown that the newly discovered plasma-redshift cosmology gives a simpler, more accurate and consistent explanation of many cosmological phenomena than the big-bang cosmology. The SNe Ia observations are in better agreement with the magnitude-redshift relation predic...
I show that the large number of objects observed with a surveying 4-m zenith telescope allows one to carry out cosmological projects at low redshifts. Examining two case studies, I show first that a variability survey would obtain light curves for several thousands of type Ia supernovae per...
We give distance-redshift relations in terms of elliptic integrals for three different mass distributions of the Friedmann-Lematre-Robertson-Walker (FLRW) cosmology. These models are dynamically pressure-free FLRW cosmology on large scales but, due to mass inhomogeneities, differ in their optical pro...
