Abstract:
This is a detailed spectral classification of 96 active galaxies from
the Veron-Cetty and Veron catalog (2010, Version 13, Cat. VII/258) of
active galaxies and quasars. These objects were identified as radio
sources using standard radio catalogs. Those galaxies which had radio
sources in at least 6 different radio bands and had been identified
spectrally in the SDSS catalog were selected. The types of activity of
these were determined using their SDSS spectra. Three diagnostic
diagrams and a direct study of the spectra were used for more certain
classification. As a result, the classifications of 85% of the objects
were changed. The radio sources in different radio bands make it
possible to construct the spectral distribution of the energy in the
radio range and to compare it with the optical activity types.
