Abstract: | Eight radio sources with signatures of interacting galaxies have been detected within the framework of the project aimed at expanding the list of giant radio galaxies based on NVSS data. The objects have a nontrivial structure in the radio band: four sources exhibit an S-shape, three sources exhibit an X-shape typical of sources at the final stage of radio galaxy merging, and one radio galaxy has a double nucleus. Using the CATS, NED, and SkyView databases, we have made the optical and radio identifications of these objects and constructed their continuum radio spectra. |
