Spectrum and Anisotropy of Cosmic Rays at TeV-PeV-energies and Contribution of Nearby Sources

Abstract

The role of nearby galactic sources, the supernova remnants, in formation of observed energy spectrum and anisotropy of high-energy cosmic rays is studied. The list of these sources is made up based on radio, X-ray and gamma-ray catalogues. The distant sources are treated statistically as ensemble of sources with random positions and ages. The source spectra are defined based on the modern theory of cosmic ray acceleration in supernova remnants while the propagation of cosmic rays in the interstellar medium is described in the frameworks of galactic diffusion model. Calculations of anisotropy are made to reproduce the experimental procedure of getting the two-dimensional anisotropy. The detailed comparison of calculations with cosmic ray data is made. We explained simultaneously the new cosmic ray data on a fine structure of all particle spectra around the knee and the amplitude and direction of the dipole component of anisotropy in the wide energy range 1 TeV - 1 EeV. Made assumptions do not look exotic, and they confirm the modern understanding of cosmic ray origin.
