Abstract (from CDS):

In this paper we present a new sample of 87 Compact Steep Spectrum radio sources (CSS) with flux density ≥0.8Jy at 0.4GHz. This sample has been selected from the B3-VLA sample with the aid of new VLA observations at 4.9 and 8.5GHz which allowed to clean an earlier selection based on VLA 1.5GHz data. Redshifts, either spectroscopic or photometric, are known for 62% of the sources. About 75% of the sources are resolved or slightly resolved in the new observations. The range of measured linear sizes is from 20h–1kpc (selection upper limit) down to ≃0.5h–1kpc, which corresponds to our resolution limit. The Largest Linear Size (LLS) distribution is well represented by the power law dN/d(LLS)∝LLS–0.6, consistent with earlier results. The majority of the radio sources smaller than 0.5h–1kpc shows a marked spectral flattening at low frequencies. The four frequency spectra computed in the range 0.4-8.5GHz display a significant steepening at high frequencies in the largest majority of cases. A considerable fraction of source components are polarized, with median values of their fractional polarization ≃6% and ≃4% at 8.5 and 4.9GHz respectively.
