Precessing Jets in the Quasar PKS B2300-189

https://www.nrao.edu/archives/plugins/Dropbox/files/Quasar2300-189_VR51_hi.jpg

Description

Precessing-beam quasi-stellar object. The bright central component coincides with a Quasi-Stellar Object (QSO or quasar) at a redshift of z = 0.128. The QSO is precessing so the radio-emitting material which it ejects traces out an S-shape on the sky. The inset in the upper left of the image shows the resolution of the VLA observations.
Observing run - 1982 June 25 at the VLA, in hybrid configuration using about 27 antennas and combined A and C data.
