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 dissipation is stronger on one side or because they flip alternately between the two lobes they supply2, or the one-sidedness may be only apparent, the result of Doppler beaming in twin relativistic jets3. So far, attempts to distinguish observationally between these two possibilities have been… 
The sidedness of jets and depolarization in powerful extragalactic radio sources
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
On the depolarization asymmetry seen in giant radio lobes
The depolarization asymmetry seen in double-lobed radio sources, referred to as the Laing-Garrington (L-G) effect where more rapid depolarization is seen in the lobe with no visible jet as 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
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
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
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
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
The Unified Schemes and Radio Polarization Studies
In the unified schemes for extragalactic radio sources, the apparent diversity of different types of sources is interpreted to be largely due to similar objects being seen with different angles of
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
Polarization asymmetry in CSS sources: Evidence of AGN fuel?
The compact steep spectrum and gigahertz peaked spectrum sources are widely believed to be young radio sources, with ages<10 6 yr. If the activity in the nucleus is fuelled by the supply of gas, one
