The structure of active galaxies is related to the activity of their nuclei. The activity of galaxies is known to be caused by the processes occurring in their central regions with sizes of less than 10 pc, luminosities of 1044 erg/s (exceeding by 3–4 orders of magnitude the typical values for normal galaxies), and masses not exceeding 1% of the total galactic mass.
