Scientific paper

We have analyzed the Lyα, Hβ and Hα line profiles of three active galactic nuclei: quasar 3C390.3 and two Seyfert 1 galaxies; Akn 120 and III Zw2. The blue- and red-shifted broad Gaussian components which are present in all considered 3C390.3 and Akn 120 lines cannot be explained by an accretion disk model because of the lines' variation on longer time-scales. On the other hand, the line profiles as well as the variation of the III Zw2 spectral line shapes can be explained by an accretion disk model. .
