The purpose of the work: Study of the inflationary mechanism of the generation of calibration fields in the early universe, confirmation or refutation of the hypothesis that dark matter can consist of ultralight Bose particles in the state of Bose-Einstein condensate, classification of quasars, analysis of obscured and Compton-thin quasars and their relationships connection, creating a catalog of X-ray galaxies. Research methods: the formalism of Green's quantum field functions, the Gross-Pitaevsky-Poisson equation, numerical methods, optical and X-ray images of galaxies. Results and their novelty: The theory was developed and model-independent estimates of the generated hypermagnetic fields in the axion inflation model were obtained using the gradient expansion formalism. The influence of the Schwinger effect - the creation of pairs of charged fermions of the Standard Model by a strong hyperelectric field - is taken into account. Magnetogenesis was studied due to the non-minimal connection of the calibration field with the curvature of space-time within the Higgs-Starobinsky inflationary model. It was established that the spectrum of the generated fields can be scale-invariant or even have a red slope, which makes it possible to obtain a larger correlation length of the magnetic field. Galactic haloes with a vortex core and an isothermal shell formed by dark matter from ultralight bosons in the Bose-Einstein condensate state were studied. A systematic analysis of the soft X-ray emission from the active nucleus of the Mgk 273 galaxy was carried out and the masses of its two components were determined.
