Head Horbar Eduard V., Доктор фізико-математичних наук Registration Date 14-07-2025 Organization Taras Shevchenko National University of Kyiv popup.description1 Study of the inflationary mechanism of generating calibration fields in the early universe; confirmation or refutation of the hypothesis that dark matter may consist of ultralight Bose particles in the state of Bose-Einstein condensate; classification of quasars, analysis of darkened and Compton-thin quasars and their relationship, creation of a catalog of X-ray galaxies. popup.description2 The cosmic inflation paradigm is very successful in explaining why our Universe is spatially flat and homogeneous and isotropic on large scales. As a result of the interaction of the inflaton field with the fields of the Standard Model, gauge fields can be generated, which naturally explains the existence of magnetic fields with very long coherence lengths in voids. During the early evolution of the Universe, all forms of matter, including baryonic and dark matter, are also formed. The goal and objectives of the project: 1) To study the generation of gauge fields in the primordial plasma of the early Universe in inflationary models; 2) To study the dynamics and interaction of dark matter structures formed by hypothetical ultralight Bose particles in the state of Bose-Einstein condensate; 3) to investigate the mechanisms of X-ray emission from active galactic nuclei of different types based on their spectra, to create new catalogs of X-ray galaxies as cross-samples with other ranges, to investigate the large-scale structure of the Universe in the X-ray range.
