Abstract
The angular sizes of compact steep spectrum sources in the Peacock and Wall sample were found to decrease steeply with redshift, similar to the angular size-redshift variation for extended sources. This, however, could be an artefact if the compact sources are not all of the same nature.Models such as those of Subramanian and Swarup with a beam power of 1037 W were found to be compatible with compact sources being either young sources at an early stage of development or relatively weak sources in dense, active media where star formation is continuing.
