A further search for objects that include line at ~ 3.55 keV is done by analyzing observations. Detection of new emission line in the center of our Galaxy and some clusters of galaxies appeared consistent with the hypothesis of the decaying Dark Matter. It is shown that the study of the intensity ratio of potassium lines in X-rays using the new telescopes with better resolution can eliminate astrophysical origin of the line. Based on own samples of active galactic nuclei (AGN) of the I type and the blue galaxies from SDSS DR7 and WiggleZ DR1 reviews the parameters of cross- (CCF) and autocorrelation (ACF) functions were obtained. Color-color diagram of central galaxies and their weak satellites were obtained. The number of pairs of different morphological types in real and random distributions were compared. The X-ray spectra of active galactic nuclei (AGN) in the 0.5-250 keV energy range were studied from the original sample of 95 objects formed on the basis of 22-month all-sky review by Swift-BAT. For the galaxies from sample, the parameters of the X-ray spectra were obtained using XMM-Newton and INTEGRAL / IBIS data. The dependance of the photon index, relative reflection parameter, cut-off energy, the equivalent width of Fe Kalpha line and the inner luminosity were obtained and studied.
