VIII/94 Catalog of extended extragalactic radio sources (Amirkhanyan, 2014) ================================================================================ Anisotropy of the space orientation of radio sources. I: The catalog. Amirkhanyan V.R. =2009AstBu..64..325A =2014yCat.8094....0A ================================================================================ ADC_Keywords: Radio sources Abstract: A catalog of extended extragalactic radio sources consisting of 10460 objects is compiled based on the list of radio sources of the FIRST survey. A total of 2339 objects are identified with galaxies and quasars of the SDSS survey and the Veron-Veron catalog. The distribution of position angles of the axes of radio sources from the catalog is determined, and the probability that this distribution is equiprobable is shown to be less than 10^-7^. This result implies that at Z equal to or smaller than 0.5, the spatial orientation of the axes of radio sources is anisotropic at a statistically significant level.
