Sizes of active galaxies

The diameters of active galaxies were compared with the diameters of ordinary galaxies. It is shown that, within the same luminosity limits, they do not differ clearly from each other. Starlike active galaxies in the samples of active galaxies have any possible luminosities. The parent galaxies of quasars have different diameters and, in accordance with their sizes, can be either elliptical or spiral.
