The B3-VLA CSS sample. VII: WSRT Polarisation Observations and the Ambient Faraday Medium Properties Revisited

We present new polarisation observations at 13 cm, acquired using the Westerbork Synthesis Radio Telescope (WSRT), of 65 sources, from the B3-VLA sample of Compact Steep-Spectrum sources. These new data are combined with our VLA polarisation data, at 3.6, 6 and, 21 cm, presented in a previous paper. Due to the multi-channel frequency capabilities of the WSRT, these new 13 cm observations enable...

The B 3 – VLA CSS sample . II : VLBA images at 18 cm

VLBA observations at 18 cm are presented for 28 Compact Steep–spectrum radio Sources (CSSs) from the B3–VLA CSS sample. These sources were unresolved in previous VLA observations at high frequencies or their brightness distribution was dominated by an unresolved steep spectrum component. More than half of them also showed a low frequency turnover in their radio spectrum. The VLBA images display...

The B 3 – VLA CSS sample . III : EVN & MERLIN images at 18 cm

EVN and MERLIN observations at 18 cm are presented for 18 Compact Steep–spectrum radio Sources (CSSs) from the B3–VLA CSS sample. These sources were marginally resolved in previous VLA A-configuration observations at 4.9 and 8.4 GHz or had peculiar morphologies, two of them looking like core–jets. The MERLIN images basically confirm the VLA structures at 8.4 GHz while the EVN and/or the combine...

VLA Measurements of a sample of Planetary Nebulae

We report on new radio measurements of Galactic planetary nebulae, aimed at resolving the controversies on the reliability of older VLA flux densities and the suggested deviations from the standard Galactic extinction law found for planetary nebulae. We show that for faint (<10 mJy) objects observed at high angular resolution, previous determinations are indeed too low. For the bright objects w...
