New observations of the angular diameter-redshift relation for radio sources

Nature volume 252, pages 657–659 (1974)Cite this article

An Erratum to this article was published on 31 January 1975

Abstract

Measurements of the angular sizes of radio source components in the range 0.1″–1.0″, using the technique of interplanetary scintillation, reveal an absence of small–diameter sources at the largest redshifts. The cosmological implications of this result are discussed.
