The B3-VLA Sample

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...

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...

Relation between blue/UV continuum shape and the ratio of radio to optical emission for B3-VLA quasars

The low frequency radio luminosity is believed to be an indicator of jet power, while the optical/UV emission is probably from accretion discs in the nuclei of steep-spectrum radio quasars. We present a correlation between the ratio of radio to optical luminosities and the continuum spectral index in blue/UV bands, which might indicate that the continuum shape in blue/UV bands is related to the...

The Vla Ultradeep Field

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...
