A study of the isolated galaxies with active nuclei is a very important to get a response
to the internal evolution of galaxy activity. Wherein, their multi-wavelength properties,
including in the X-ray range, are not fully analyzed as concerns with the influence of halo
matter (baryonic/dark) on the formation and productivity of AGN’s engine.
With this goal we have selected several isolated AGNs from 2MIG catalogue, for which the
available X-ray data were accessed. Among these objects are CGCG 179-005, NGC 6300, NGC 1050, NGC
2989, WKK 3050, ESO 438-009, and ESO 317-038. We have analyzed the spectral data obtained by XMMNewton, Swift, Chandra, and INTEGRAL space observatories for each of these galaxies to determine
corresponding spectral models and values of their parameters. For each galaxy we obtained an
estimate of the spectral index and intrinsic absorption. For bright galaxies, NGC 6300 and
Circinus, the X-ray spectra were analyzed up to 250 keV and their characteristics of emission
features in 6-7 keV were obtained. The results, spectral models, and current problems are
discussed.
