Modulation of the galactic cosmic ray spectrum in an anisotropic diffusion approach

We introduce a novel diffusion model for the propagation of cosmic rays (CRs) that incorporates an anisotropic diffusion tensor of a general form within a realistically modeled large-scale Galactic magnetic field. The parameters of the model are consistent with the contemporary understanding of the large-scale Galactic magnetic field structure and the dynamics of small-scale turbulent CR propagation. The paper demonstrates the modulation of spectra of Galactic cosmic rays (GCRs) in the magnetic rigidity range of 1 - 30 PV (the CR knee) and explores the spatial variation of this phenomenon. The observed modulation of the spectrum is explained by changes in the leakage mechanism.

Study of spatial inhomogeneities of cosmic rays in a synthetic turbulent magnetic field

The paper presents a theoretical model describing the full power spectra of synchrotron radiation generated by relativistic electrons in a turbulent magnetic field. Using the theoretical model, numerical calculations of the complete power spectra of synchrotron radiation were performed for a turbulent field generated by the harmonic method. Additionally, a model sky map was constructed, demonstrating the structure of the spatial inhomogeneity of the synchrotron radiation power distribution as seen by an observer.
