- Аннотация: The results of kinematical study of ionized gas for the central parts of Seyfert galaxies Mrk 34, 78, and 270, obtained with the long-slit spectrograph at the prime focus of the 6-m telescope of the Special Astrophysical Observatory, are presented. Mrk 34 and 78 are found to possess dynamically distinct central gaseous disks; the central disk of Mrk 34 counter-rotates relative to the external parts. The authors confirm the existence of radial gas flows in Mrk 34 and Mrk 78 with the relative line-of-sight velocities up to 750 km/s; there are some arguments in favor of gas inflow onto the nuclei in both galaxies. In Mrk 270 they have found two gas flows oppositely directed near each radio lobe. These facts contradict the jet hypothesis in the galaxies under consideration.
