Abstract
The authors attempt to show that the results of Heeschen on extra-galactic radio sources can be simply interpreted in terms of a consistent evolutionary sequence. They suggest that only three stages of evolution are required: particle injection into a jet-like structure; adiabatic expansion of a relativistic gas; and, finally, pressure equilibrium with the inter-galactic gas. This suggests that the quasars are at cosmological distances.
