Parsec Scale Properties of Radio Sources
We present a new complete sample of radio sources selected from the B2 and 3CR catalogues, with no bias respect to the jet velocity and orientation. Using preliminary data we investigate the parsec scale properties of radio sources with different radio power and kpc scale morphology. We stress the evidence for high velocity pc scale jets in all sources and conclude that the properties of parsec...
متن کاملThe radio source OQ208: parsec-scale morphology and spectral properties
We present results from global VLBI (Very Long Baseline Interferometry) observations at 5 GHz of the radio source OQ208. The milliarcsecond (mas) morphology of the radio emission is described by an asymmetric compact double structure with a flux density ratio between the two components of about 10:1, and a projected total size of ∼ 7 mas (i.e. ∼ 7 pc). Both components are resolved by the presen...
متن کاملObscuration of the Parsec Scale Jets in
We present results of VLA and VLBA observations of the 1.420 GHz neutral hydrogen absorption associated with the Compact Symmetric Object 1946+708 (z=0.101). We nd signiicant structure in the gas on parsec scales. The peak column density in the Hi (N HI '2.210 23 cm ?2 (Ts 8000K)) occurs toward the center of activity of the source, as does the highest velocity dispersion ((V FWHM '350 km s ?1)....
متن کاملconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
Clues to the origin of parsec to kilo-parsec jet misalignments in EGRET sources
The apparent position angle difference ∆PA between parsec and kilo-parsec jets in blazars can be related to the bending properties of the jets. We present correlations between the misalignment ∆PA and the ratio of radio to broad-line emission for a sample of γ-ray blazars. The present study is limited to EGRET sources due to uniform data for the radio and optical properties of these sources bei...
