Object of study: Early Universe, Dark Energy (TE) and Dark Matter (TM); active nuclei of galaxies (AYAs) and galaxies with a starburst; powerful gravity and electromagnetic fields and black holes; pulsars and magnets, supernova remnants.
Purpose: nature determination and identification of CPNVE sources; elucidation of the effect of background radiation and magnetic fields in galactic and extra-galactic systems on the propagation of CPs and multitone photons; search for constraints on the TE and TM models and possible effects of new physics in astrophysical and cosmological processes, clarification of the structure of the "central machine" of the SNF.
Methods of research: methods of theoretical physics and astrophysics, mathematical statistics and regression analysis, numerical modeling.
Contribution of the contribution of active galaxy (AYG) nuclei to the observed cosmic ray fluxes from particles accelerated in relativistic flows on the basis of multichannel data and the probable sources of different types of cosmic rays of extremely high energies (KEPEG) among different classes are determined. This interpretation of the hot spot in the distribution of CPNVE detected by the Telescope Array detector is given. The contributions of primary and jet radiation to the spectra of the active nucleus of the radio galaxy 3C111 are separated according to space missions for 12 observation periods. Model profiles of thin lines in the emission spectra from accretion disks in the SNF are calculated.
The light curves in high-gain galactic microlensing events have been worked out, and based on these data, a new approach to validating the relativistic formula for gravitational refraction has been developed. The efficiency of models of the origin of magnetic fields in the Universe is estimated; A new model for the origin of a cosmological magnetic field based on a helical coupling in the Lagrangian of an electromagnetic field is proposed.
