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 ...

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.

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 ...

Astrophysical Jets: Optical Morphologies of Radio Jets and their Parent Galaxies

1983
We discuss the relevance of optical observations for a better understanding of the nature of cosmic jets and of the phenomena related to them. We insist in particular on the morphology of the optical jets known as yet, especially that of M87, from high-resolution observations. We also discuss the new insights that the detection of interstellar dust can

Bent Jets and Tailed Radio Galaxies

1983
The observationally defined properties of tailed radio sources are reviewed with particular emphasis on the characteristics of bent jets. A comparison is made between the structures found in straight and bent jets. It is demonstrated that the curvature of jets associated with narrow-angle tailed galaxies can provide a strong constraint on the average ...
