Annals of the New York Academy of Sciences, 1974
The discrete sources of radio emission were first distinguished from the general background radiation during the 1940’s as a result of their rapid amplitude scintillations ; and initially, it was thought that the scintillations were due to fluctuations in the intrinsic intensity of the discrete sources. Assuming that the dimensions of the sources could

Cosmological Evolution in Radio Galaxies

Nature, 1971
ROWAN-ROBINSON has presented evidence that radio galaxies exhibit remarkably strong evolutionary effects with cosmological epoch1. Examination of his evidence, however, indicates that, although an evolutionary effect may indeed be present, no reliable estimate of the time scale involved can yet be made in the way he proposes.

Radio Map of the Andromeda Galaxy

Science, 1964
The University of Illinois radio telescope has resolved the 610.5 Mcy/sec disk component of radio emission from the large galaxy M 31 into several discrete concentrations. In two cases, these correspond to the crossing of the optical major axis by spiral arms. A spur of emission extends southeast from the galaxy near the minor axis.
