“…It has been extensively studied in the past at different radio wavelengths. At kpc scales, the maps reveal components south of the core at 2, 37, and 45 arcsec (Antonucci et al 1986;Strom & Biermann 1991;Murphy et al 1993). Eckart et al (1987) and Pearson & Readhead (1988) reported a core-jet structure at pc scales with a jet oriented westwards.…”

“…Its radio structure has been studied at pc and kpc scales by Appl et al (1996), who reported a misalignment of the jet between both scales. At kpc scales, Murphy et al (1993) reported a VLA map with a core and a fainter component at 6 arcsec and PA ∼ −100 • . At pc scales, Eckart et al (1987) reported a core-jet structure in the VLBI maps, with a faint jet emission oriented at .93) and 28 May 1999(1999.…”

Abstract. We observed the thirteen extragalactic radio sources of the S5 polar cap sample at 8.4 GHz with the Very Long Baseline Array, on 1997.93 and 1999.41. We present the maps from those two epochs and briefly discuss the morphological changes experimented by some of the radio sources in the 1.4 yr elapsed. These results correspond to the first two epochs at 8.4 GHz of a program directed to study the absolute kinematics of the radio source components of the members of the sample by means of phase delay astrometry at 8.4, 15 and 43 GHz.

“…Except for that, there is a significant decrease in the flux density at 408 MHz, suggesting a low frequency turnover around 1 GHz in the spectrum. The Very Large Array (VLA) observation performed at 1.5 GHz in 1984 revealed a bright compact component and a weak feature about 4.9 ′′ to the southwest (Murphy et al, 1993).…”

Most of the γ-ray emitting active galactic nuclei (AGN) are blazars, although there is still a small fraction of non-blazar AGN in the Fermi/LAT catalog. Among these misaligned γ-ray-emitting AGN, a few can be classified as Compact Symmetric Objects (CSOs). In contrast to blazars in which γ-ray emission is generally thought to originate from highly beamed relativistic jets, the source of γ-ray emission in unbeamed CSOs remains an open question. The rarity of the γ-ray emitting CSOs is a mystery as well. Here we present the radio properties of the γ-ray CSO candidate 2234+282.

“…This is a misaligned source, with its VLA jet at almost 90 degrees position angle to the Very Long Baseline Array (VLBA) jet (Murphy et al 1993;Britzen et al 2007). A jet in the western direction with a sharp bend to the south at about 50 mas was detected by Polatidis et al (1995) observations at 5 GHz (Barthel et al 1995).…”

A kinematic study of the compact jet in quasar B3 1633+382

We present a study of the motion of compact jet components in quasar B3 1633+382. Through analyzing 14 epochs of VLBI observations of three components (B1, B2, and B3) at 22 GHz, we find two different possibilities of component classification. Thus two corresponding kinematical models can be adopted to explain the evolutionary track of components. One is a linear motion, while another is a helical model. Future observations are needed to provide new kinematical constraints for the motion of these components in this source.
