%T Propagation and radiation of ultrarelativistic particles in magnetic fields in different astrophysical environments
%U https://archiv.ub.uni-heidelberg.de/volltextserver/15234/
%X The thesis work presents the results of theoretical studies of different scenarios for the propagation  and the radiation of ultrarelativistic particles depending on the environment determined  by the magnetic and low energy radiation fields.  First, using the analytical solution of Boltzmann equation in the small-angle approximation,  we have accurately calculated the angular, energy, and time distributions of the ultrahigh  energy protons, gamma rays produced by synchrotron radiation of secondary electrons and  positrons, and secondary neutrinos from the source of cosmic rays embedded in the magnetized  environment of the level of B ∼ 10^(−9) G.  The second part considers the scenario explaining TeV gamma radiation from distant blazars  by secondary gamma rays produced by cosmic rays along the line of sight in the weak magnetic  field of the level of B ∼ 10^(−15) G. We have studied the possibility of detection of TeV radiation  from blazars with redshifts greater than z = 1.  Finally, the last chapter of the work is addressed to the radiation of charged particles in the  extremely strong magnetic fields of compact objects such as pulsar and black hole. We have  studied the synchrotron and curvature radiation regimes and transition between them showing  the strong sensitivity of radiation spectra on the pitch angle.
