Radio Galaxies and Quasars

  • Kenneth I. Kellermann

Abstract

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 not greatly exceed the distance traveled by light during a typical fluctuation period of about 1 minute, it was concluded that the discrete sources were galactic stars located at relatively small distances from our solar system. Thus the term “radio star” was often used in referring to these sources.
