Jets in Active Galaxies

Resonance, 2018
Jets in active galaxies are signatures of energy supply via collimated beams of plasma from the galactic nucleus to the extended regions of emission. These jets, which occur across the electromagnetic spectrum, are powered by supermassive black holes in the centres of the host galaxies.

Are There Jets in Spiral Galaxies?

1983
The absence in spiral galaxies of large-scale collimated jets of radio emission is still little understood. Collimated emission in elliptical galaxies in some cases exceeds by far the optical extent of the galaxy (e.g. in NGC6251). Westerbork observations of NGC4258 (van der Kruit, Oort and Mathewson, 1972) and NGC3079 (de Bruyn, 1977) have provided ...

Classification of Optical Jets in Galaxies

1986
New, deep images of galaxies reported in various catalogs to have optical jets show that most are not jets, but tidal features, polar rings, or superpositions. From those objects that do seem to represent nuclear ejecta, criteria of brightness relative to the parent galaxy, width, and location have been derived, which should produce much purer samples ...

The Jets in Radio Galaxy B1308–441

Publications of the Astronomical Society of Australia, 1996
AbstractThe giant radio galaxy B1308–441 has prominent two-sided jets, typical of Fanaroff–Riley class I radio galaxies, but there is an unusual bright spot in the SE jet 2 arcmin from the core that gives a marked asymmetry to the source. Observations at 1·37 and 2·37 GHz with the Australia Telescope Compact Array show that the bright spot has a ...
