Radio-frequency Studies of Galactic Structure,short wavelengths (. = 14.6 m) he observed that part of this noise came preferentially from a certain azimuth. From the variation of this azimuth with the time of the day, and with the time of the year, he concluded that the source was related to the nuclear region of the Galactic System.

Star Clusters,pes of stellar populations puts them in the spotlight since galactic clusters represent population I and globular clusters population II. The increasing development of theories of stellar evolution rests on star clusters, which furnish a group of stars presumably created from the same material at ab

Discrete Sources of Cosmic Radio Waves,high intensity which are described by the term .. At the present time our knowledge of the nature of these sources is very limited and the description . is correspondingly vague. No attempt will be made here to define precisely what is classed as a discrete source, except to state that the term has

Radio Frequency Radiation from External Galaxies,sion from a region in the constellation of Cygnus. They deduced that the fluctuating component “could only originate from a small number of discrete sources”. This was confirmed when . and .. showed that the fluctuations were due to an intense emitting region less than eight minutes of arc in extent

General Physical Properties of External Galaxies,The order of magnitude of their dimensions, luminosities and masses was established over thirty years ago by . [.] and by . [.].

Large Scale Organization of the Distribution of Galaxies,hese ideas is that the galaxies are clustered, and the other is that the large-scale organization of the distribution of galaxies is statistically uniform. Occasionally, the possibility of higher order clustering of galaxies is also mentioned.
