Samples of CSS/GPS sources suitable for statistical studies have been selected from the 3CR catalogue and from the Peacock & Wall catalogue. The selection criterion used for the Peacock & Wall catalogue CSS/GPS sources selects sources which peak below about 2GHz and are therefore larger than ~200pc. Our main aim is to find among the flat spectrum sources in the Peacock & Wall catalogue smaller size CSS/GPS sources by means of systematic high resolution observations. The discovery of a few more would be important in order to finally have a complete flux limited sample of this class of objects. We discuss the results obtained so far for three of the observed sources.

Abstract
Samples of CSS/GPS sources suitable for statistical studies have been selected from the 3CR catalogue and from the Peacock & Wall catalogue. The selection criterion used for the Peacock & Wall catalogue CSS/GPS sources selects sources which peak below about 2GHz and are therefore larger than ~200pc. Our main aim is to find among the flat spectrum sources in the Peacock & Wall catalogue smaller size CSS/GPS sources by means of systematic high resolution observations. The discovery of a few more would be important in order to finally have a complete flux limited sample of this class of objects. We discuss the results obtained so far for three of the observed sources.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
