OBSERVATIONS OF THE RADIO GALAXIES NGC-315 AND 3C-219 AT 102-MHZ

Observations of the radio galaxies NGC 315 and 3C 219 were conducted a t 102 MHz, using the interplanetary scintillation method. Upper limits of the flux densities for the compact components in the nuclei of the se galaxies were obtained. Supposing that their low-frequency cutoff i s caused by synchrotron self-absorption, the estimates of the magnetic field strength H less-than-or-equal-to 10(-2), energy of the magnetic field E(H) approximately 10(49) and of the relativistic electrons E(e ) approximately 10(50), within the scale of approximately 1 pc, were o btained. Radio images of the galaxies were drawn, and total flux densi ties were estimated. Comparison of the results of this work with simil ar investigations of the radio galaxies 3C 236, DA 240 and NGC 1275 po ints to the possible relationship between morphological type of radio galaxies and physical conditions in the nucleus of the parent galaxy. For nuclei of galaxies of classical morphology, with giant radio cloud s connected by jets with the nucleus, the energy of a magnetic field c onsiderably exceeds the energy of relativistic electrons. The opposite is true for jetless galaxies; for tailed galaxies an approximate equi partition is observed.
