Polarization, Bl Lacertae Objects: General, Radio Continuum: Galaxies
Scientific paper
We present Very Long Baseline Array (VLBA) 5-GHz polarimetric observations of 23 BL Lacertae (BL Lac) objects and radio galaxies selected from the 200-mJy sample. BL Lac objects have core polarization values lower than those found in previous samples. The magnetic field geometry in the jets is not unique: both parallel and perpendicular geometries are observed, even in the same sources. The parsec-scale morphology of radio galaxies is clearly divided in two classes: one-sided core-jet sources, which show polarized emission in the core and/or jet, and two-sided symmetric objects which are not polarized. We discuss and compare the parsec-scale polarization properties of the radio cores and jets for the BL Lac objects and the radio galaxies in relation to their parsec-scale morphology and high-frequency integrated spectral index.
