Scientific paper

Analytical and numerical methods have been used to develop a dynamical model for the evolution of the linear size, D, of compact steep spectrum (CSS) sources through the ambient medium of density, ne, within a characteristic time, T. This shows that the empirical relation between spectral turnover, νp, and D implies that νp ~ n0.35e, suggesting that the spectral turnover constitutes a characteristic signature of dense gases around CSS sources.
