Abstract

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. Jets are seen on the scale of parsecs in the nuclear regions to those which power the giant radio sources extending over several megaparsecs. These jets raise many challenging astrophysical questions. This article explores some aspects of jets in radio galaxies and quasars, which are amongst the most powerful active galaxies.
