Compact Radio Sources [PDF]
Symposium - International Astronomical Union, 1981 SummaryThe observational data on the radio properties of compact radio sources are presented, including their radio spectra, their occurence, and their structures, as well as the variations of the structures in the “superluminal” sources.K.

Journal of Astronomy and Space Sciences, 2003 The motion of 3C120 Jet relative to the core is reasonably uniform and the VLBI scale jet connects outwards to a VLA ˜ 100 kpc scale. We measured the jet width variation from the center and found some indication of a power law which indicates the jet ...Siek Hyungdoaj +1 more sourceSuperluminal Radio Sources [PDF]
Symposium - International Astronomical Union, 1988 There are now at least 23 radio sources in which apparent superluminal motion has been found. The effect is not limited to the “classic” examples like 3C 345, but is found in objects with a wide range of characteristic properties. We review the observations of the phenomenon and present an up-to-date list of the known superluminal sources.Zensus, J. A., Pearson, T.

Symposium - International Astronomical Union, 1969 Following the advice of Professor Zel'dovich, I will begin with two platitudes – first, when we consider the implications of the counts of radio sources, we must look at all the counts of radio sources at all frequencies; second, when we attempt to evaluate the implications of the source counts, we should use proper cosmological models and not rely on ...openaire +1 more sourceSources of the Radio Background Considered [PDF]
