We study regions with radius of 500 pc around of the central radio galaxies from our sample. For this study were chosen about 30 nearby 3C radio galaxies of different FR types. We bring the maps of optical galaxies that are overlaid on the radio map of 3C radio source. It was used also the maps of these regions in all available wavelength. Here we present more detail analyses and new results for the radio galaxy of FRI type 3C31. The dependencies of the morphological types of the first and second ranked group galaxies on the magnitude gap were studied. It is shown that there is no increase in the relative number of elliptical galaxies among the first and second ranked group galaxies with large magnitude gaps. Some results are presented on studies of a sample of about hundred galaxies (“100SBS”) from two adjacent fields of SBS, which have spectral data in SDSS. Comparative analysis was done between two classifications that the 100SBS objects got - from one side Starburst or Starforming in SDSS, from the other - SfGcont and SfGneb, with a possibility of further detailing in accordance to our scheme for star-forming galaxies.

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
