“…These large differences in morphology and physical properties of different classes of extragalactic radio sources can be due to differences in parent optical galaxies or in differences of the extragalactic medium around the radio source in which the radio source is expanding. In order to reveal the influence of the environment on extragalactic radio source, we study the close proximity (regions with radius of 500 pc around of the central radio galaxies) of the well-known Giant radio sources 3C 31, 3C 449, NGC 315, NGC 6251 from our sample of about 30 nearby 3C radio galaxies of different FR types chosen from Andreasyan & Abrahamyan (2021). .…”

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.

“…2 right); a correlation of the ellipticity of parent optical galaxies associated with radio galaxies of different classes (Andreasyan & Sol, 2000) (Fig 3), etc. For the study we use data of nearby extragalactic radio sources from our samples (Andreasyan & Abrahamyan, 2021). In these samples we have data for 267 nearby radio galaxies identified with elliptical galaxies brighter than 18 th magnitude (sample1) and 280 extragalactic radio sources with known position angles between the integrated intrinsic radio polarization and radio axes (sample 2).…”

We study the environment of nearby extragalactic radio sources of different morphological type from our sample. We chose 30 3C radio galaxies of different FR class for which we have several observational dates on wavelength from radio to X ray. For the study we select the regions with radius of 500 pc around of the parent galaxy of radio sources. We bring the optical maps of these regions that are overlaid on the radio maps and maps in all available wavelength. The preliminary review show that there are some differences in the neighboring regions around radio galaxies of different FR classes.
