Properties of Radio Source Host Galaxies

A brief overview of the current radio source host galaxy state of affairs is given. All the evidence appears to point towards a scenario in which the young radio source expands through the host galaxy on timescales of 10⁵-10⁶yr, before it ends its life as a large scale FRII radio galaxy. The place and role of the quasars in this evolutionary picture is unclear, however, and remains an issue of debate.
