A database of X-ray galaxy clusters, observable by space telescopes Swift, Suzaku, XMM-Newton, Chandra, and NuStar and Integral was created. The database is replenished with new data and is used to construct accumulated density profiles of temperature, luminosity and distribution of density profiles of the baryonic / hidden mass of these galaxy clusters. For four isolated galaxies with active nuclei at redshifts to z <1, the spectral characteristics were first calculated from the data of the NuStar Observatory. The distribution of the decomposition line of dark matter on the energy of 3.5 keV in the observations of the central parts of our Galaxy and Andromeda galaxy, investigated within the framework of the project of building a map of the sky in the X-ray range, has been analyzed. A semi-analytic method for describing the distribution of density in a halo of warm dark matter formed from fermions has been developed. The methods of studying the Zone of Avoidance in order to reconstruct the large-scale distribution of galaxies, which closes this zone of Milky Way, are developed, taking into account data in X-, IR-, and radio ranges. The algorithms of machine learning methods for the analysis of physical characteristics of galaxies and their distribution are developed.  Product Description popup.authors Babyk Yurii V.
