A New Intense Source of Radio-Frequency Radiation in the Constellation of Cassiopeia

Nature volume 162, pages 462–463 (1948)Cite this article

Abstract

THE discovery by Hey, Parsons and Phillips1,2 of a variable source of radio-frequency radiation in the constellation of Cygnus suggested that at least part of the galactic radiation was due to very intense discrete sources. Afterwards a detailed study of this region was made by Bolton and Stanley3, using an interference system of greater resolving power ; their results showed that the angular diameter of the source was smaller than the resolving power of their apparatus (8 minutes of arc), and the more precise determination of its position enabled them to show that the source does not coincide with any outstanding star. In a more recent note Bolton4 describes the extension of this work and the discovery of other discrete sources.
