The cause of one-sidedness in the jets of otherwise symmetrical extragalactic radio sources is a subject of some controversy1. There is good evidence for relativistic bulk motion in the cores of these objects (from observations of apparent superluminal motion, rapid variability and the absence of inverse-Compton X-rays)2. A natural hypothesis is then that jets are intrinsically two-sided and that they remain relativistic on all scales3, the jet closer to us appearing bright as a result of… 
Jets, Hot Spots, and Sidedness in Double Radio Sources in the Slingshot Theory
The origin of jets and hot spots in FR II double radio sources are explained by a model in which a supermassive black hole possessing twin beams moves out of the host galaxy with a speed greater than
A new class of extragalactic radio sources with one-sided structure?
EXTRAGALACTIC radio sources with extended emission on only one side of the active galaxy usually have very dominant radio cores1–5, large misalignments between the structure inferred from Very Long
A systematic asymmetry in the polarization properties of double radio sources with one jet
It has long been a puzzle why high-luminosity extragalactic radio sources, which are symmetric in many respects, have jets on one side only1.The jets may be intrinsically asymmetric, because
Extragalactic sources with very asymmetric radio structure: VLA and MERLIN observations
As part of our study to understand the nature of extragalactic radio sources which are very asymmetric in the surface brightness of the two lobes, often with radio emission on only one side of the
A counterjet in the elliptical galaxy M87
JETS in radio galaxies have a variety of observed morphologies, in particular appearing in both one-sided and two-sided forms. It is not known whether jets can be intrinsically one-sided, or if the
Relativistic Motion on Kilo-Parsec Scales in Powerful Radio Sources
Strong evidence already exists for relativistic motion on parsec scales (su-perluminal motion and variability, and also relations between radio core dominance and optical characteristics). Evidence
A relativistic model of the radio jets in 3C296
We present new, deep 8.5-GHz VLA observations of the nearby, low-luminosity radio galaxy 3C 296 at resolutions from 0.25 to 5.5 arcsec. These show the intensity and polarization structures of the
On the Asymmetries in Powerful Extragalactic Radio Sources
We have investigated the correlations between the asymmetries in depolarization and spectral index in a bright source sample. We find a significant correlation between these asymmetries which can be
Large-scale superluminal motion in the quasar 3C273
THE quasar 3C273, one of the first discovered1, is optically the brightest example of a source with a one-sided jet. It was also the first object to display apparent superluminal motion on parsec
Depolarization Studies of Radio Sources and the Unified Scheme
In powerful FRII radio galaxies and quasars the polarization of the two radio lobes is often very asymmetric and strongly correlated with jet sidedness. These sources usually have one-sided jets and
