Markarian galaxies with double and multiple nuclei

Extract

Saakian, Petrosian and I have studied the central regions of Markarian galaxies using observations made with the SAO 6-metre telescope and the 2.6 m and 0.5 m telescopes of the Burakan Observatory. in a paper soon to be published, we show that in those galaxies which have strong ultraviolet excesses, i.e. Markarian Galaxies, double or multiple nuclei are found with a significantly greater frequency than they are in ordinary galaxies. This result suggests that these are among the most active nuclei. the photographs in our paper show the 60 examples of double or multiple nuclei found in the first 8 lists of Markarian galaxies.
