The Quasar CTD 135 Is Not a Compact Symmetric Object
The radio-loud quasar CTD 135 (2234+282, J2236+2828) has been proposed as a candidate compact symmetric object (CSO), based on its symmetric radio structure revealed by multi-frequency very long


Compact symmetric objects and supermassive binary black holes in the VLBA Imaging and Polarimetry Survey
We present multi-frequency Very Long Baseline Array (VLBA) follow-up observations of VLBA Imaging and Polarimetry Survey sources identified as likely compact symmetric objects (CSOs) or super-massive
The milliarcsecond structure of a complete sample of radio sources. II: First-epoch maps at 5 GHz
VLBI observations of the compact radio structure in a sample of 65 powerful extragalactic radio sources are presented. The sources are classified as very compact, compact, asymmetric, compact double,
Optical and Infrared Polarization of Active Extragalactic Objects
In bringing together the material for this review our attention was drawn repeatedly to the remarkably similar characteristics of virtually all strongly polarized extragalactic objects, which are
We present very long base interferometry (VLBI) images of the compact high-luminosity radio galaxy 2352+495 that show symmetric structure on either side of a prominent central core. This contrasts
Evidence for two classes of parsec-scale radio double source in active galactic nuclei
There is a group of powerful compact radio sources which have two almost equal flux density components on parsec scales. On the basis of multifrequency, multiepoch Very Long Base Interferometry
The Relativistic Jet Orientation and Host Galaxy of the Peculiar Blazar PKS 1413+135
PKS 1413+135 is one of the most peculiar blazars known. Its strange properties led to the hypothesis almost four decades ago that it is gravitationally lensed by a mass concentration associated with
TXS 0128+554: A Young Gamma-Ray-emitting Active Galactic Nucleus with Episodic Jet Activity
We have carried out a Chandra X-ray and multifrequency radio Very Long Baseline Array study of the active galactic nucleus (AGN) TXS 0128+554, which is associated with the Fermi γ-ray source 4FGL
The compact triples 0710 + 439 and 2352 + 495 - A new morphology of radio galaxy nuclei
The compact radio sources 0710+439 and 2352+495 have each been mapped using intercontinental VLBI arrays at frequencies of 5.0 and 10.7 GHz. The source 0710+439 has also been mapped at 1.7 GHz. Both
New Limits to the Angular Sizes of Some Quasars
IN previous experiments at Jodrell Bank the angular sizes of discrete radio sources have been investigated by means of long baseline interferometers1,2. The highest resolving power used previously
Compact Features in a Complete Sample of Radio Sources
The occurrence of compact features in a complete sample of 3 CR sources, as revealed by interplanetary scintillation at 8r5 MHz, is described. It is found that ' hot spots ' having a typical size of
