On the Numerical Stability of the Diffusion Coefficient in Microscopic Simulations
Vladimir Yurovsky, Ilya Kudryashov
Nowadays, the calculation of the Galactic Cosmic Rays diffusion coefficient with direct microscopic numerical simulations is a widespread approach. In this work, we investigated th…

Modulation of the galactic cosmic ray spectrum in an anisotropic diffusion approach
V. D. Borisov, V. O. Yurovsky, I. A. Kudryashov
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 lar…

Spatial dependence of the break in the energy spectrum of cosmic rays in the new anisotropic diffusion approach
Vladislav Borisov, Vladimir Yurovsky, Alexandra Peryatinskaya +1
At present, there is no consensus on whether the spectral break in the cosmic-ray flux of all elements around 4 PeV is a general characteristic of the Milky Way or is determined by…
