... The author of the cover picture is Vasilisa Verkhodanova. The picture symbolizes our perception of the world. The modified emblem of the SAO unifying the 6-m optical telescope and the raditelescope RATAN-600 of SAO RAS is placed in the center of the radio galaxy isophotes. From the one hand, we can investigate the properties of radio galaxies with these (and other) telescopes, and try to study physical processes providing their activity. ...
