NED Abstract

Copyright by Royal Astronomical Society. 2010MNRAS.408.2256E The spectral turnover-linear size relation and the dynamical evolution of compact steep spectrum sources Ezeugo, J. C.; Ubachukwu, A. A. Abstract. ABSTRACT 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, n_e_, within a characteristic time, T. This shows that the empirical relation between spectral turnover, {nu}_p_, and D implies that {nu}_p_ ~ n^0.35^_e_, suggesting that the spectral turnover constitutes a characteristic signature of dense gases around CSS sources. Key words: methods: analytical, ISM: evolution, galaxies: active, galaxies: evolution, galaxies: ISM, galaxies: jets
