Abstract

We present the results of (2.3/8.3 GHz) VLBI snapshot observations of 28 sources drawn from a list of Compact Steep-Spectrum (CSS) and GHz-Peaked Spectrum (GPS) candidates by Dallacasa & Stanghellini (1991) with additional sources from Barthel et al. (1988) and from Wills (1979). The experiment was carried out with 4 stations of the European VLBI Network (EVN) with the addition of two geodetic antennas. Typical resolutions were about  mas and  mas at S and X bands respectively. Only one source was not detected. Due to the limited uv-coverage of the data, only simple structures could be imaged.
