European VLBI Network dual frequency observations of CSS-GPS candidates.

DALLACASA D., BONDI M., ALEF W. and MANTOVANI F.

Abstract (from CDS):

We present the results of S/X (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, in Proc. of "Compact Steep-Spectrum and GHz-Peaked Spectrum Radio Sources.", p. 224) with additional sources from Barthel et al. (1988A&AS...73..515B) and from Wills (1979ApJS...39..291W). 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 30x12mas and 9x3.5mas 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.
