Red-shifts and Power Outputs of Quasi-stellar Radio Sources

Naturevolume 212pages165166 (1966) | Download Citation



Hoyle and Burbidge1 have recently expressed the opinion that the red-shifts found in the spectra of the quasi-stellar objects are not related to distances. We believe that this view is unduly pessimistic and that the quasi-stellar radio sources can indeed be satisfactorily interpreted on a cosmological basis. Our reasons for making this statement are based on the construction of a log z versus mr diagram for known radio galaxies and the analysis of a somewhat similar diagram for the quasi-stellar sources which, given the cosmological interpretation, leads to results consistent with the log N-log S diagram.
