Scientific paper

In this paper the analysis of the emission line spectra of Seyfert galaxies is continued in the light of the composite models for the narrow line region of active galactic nuclei. The model accounts for the coupled effect of photoionization and shock waves in determining the physical conditions in the emitting clouds. Therefore, some calculations about densities and temperatures in the postshock region are presented in the range of the observed values, and correlations with shock velocities are discussed. The observed data of a particular group of galaxies, called intermediate Seyfert galaxies (Cohen, 1983) are compared to model calculations. From the point of view of narrow lines, the results show that Seyfert type 2, intermediate Seyfert galaxies, and Liners may be interpreted as different aspects of the same phenomenon, depending only on the relative importance of photoionization and shock effects in determining the physical conditions of the emitting region.
