Collimation of extragalactic radio jets
New Astronomy Reviews, 2002Abstract We study the collimation of radio jets in the high-luminosity Fanaroff–Riley class II sources by examining the dependence of the sizes of hotspots and knots in the radio jets on the overall size of the objects for a sample of compact steep-spectrum or CSS and larger-sized objects.

LS 5039 is a high mass X-ray binary whose optical counterpart is a bright (V = 11) star of 07 V((f)) spectral type, at an estimated distance of 3.1 kpc. The radio emission from LS 5039 is persistent and its radio spectrum is clearly non-thermal. Here we report VLBA and VLA observations which reveal that LS 5039 is resolved into bipolar radio jets ...

Jets in extragalactic radio sources
AIP Conference Proceedings, 1979Particle acceleration in the extended parts of radio galaxies seems likely from a number of arguments. The radio jets which now seem commonly to connect the nucleus to the more extended structure of radio galaxies are a likely location for some of the necessary in situ acceleration.

Abstract Conditions that may lead to jet precession as well as extragalactic radio sources that can be interpreted as such are reviewed. Attempts to calculate model brightness distributions for these and some related sources are discussed, with specific attention for “preferential avoidance” patterns and one-sided jets.
