Spectral models of various modifications were used to correctly account for the background of the stellar component in the intergalactic gas composition. Using such models, the temperature, flux, luminosity, metallicity, and other spectral characteristics of intergalactic gas were precisely determined. Radial distributions of the physical parameters of hot atmospheres in clusters, groups, and some galaxies have been constructed. Spectral analysis of data of observations of the active nucleus of the Seyfert 1 galaxy with narrow LEDA 2816068 narrow lines in the range of 0.3-10 keV using phenomenological models, the temporal analysis of light curves in different energy ranges and the results of further spectral analysis using complex physical models were obtained accretion disk around the supermassive black hole and the parameters of its crown. The X-ray image of the interacting galaxy NGC 6240 was processed, spectral analysis was performed, and the mass of a double supermassive black hole was estimated. An evolutionary model of the Vela supernova remnant and the Vela pulsar-wind nebula have been developed. We have calculated the contributions to the observed surface brightness maps in the radio band of the supernova Sail balance and the pulsar-wind nebula. We calculated the spectra of non-thermal radiation of the complex of the Supernova Sail residue and the pulsar-wind nebula from the radio to the gamma band, taking into account the processes of acceleration of relativistic   Product Description popup.authors Babyk Yurii V.
