VLA polarimetry of compact steep spectrum sources.

Abstract (from CDS):

We present the polarization properties at sub-arcsecond resolutions of 8 Compact Steep-spectrum Sources (CSSs) observed with the VLA A-array at 5, 8.4 and 15GHz. We find that the three most compact sources, two of which are unresolved and have an angular diameter <100milliarcsec are not polarized. Of the remaining 5, the two associated with quasars have prominent radio jets while the two galaxies and one unidentified object are dominated by their lobe emission. The components of these medium sized objects with median values of percentage polarization of about 9% at 5GHz and 11% at 8.4GHz, are more strongly polarized than the compact sources and do not show evidence of very large rotation measures.
