摘要：
The spectral and kinematic properties of GPS and CSS radio sources and methods for determining their ages are discussed. The data presented here do not support a mechanism of accretion of dust or molecular gas on massive black holes located in the central regions of radio galaxies of these classes as the source of their activity. The nature of GPS and CSS objects has not been fully clarified. Further detailed studies in the optical, radio, and other spectral ranges will be required in order to establish the true nature of this class of source.
