摘要

A unique possibility to determine more exactly the contribution from nearby supernovae to cosmic rays (CRs) observed near the Earth has appeared thanks to new FERMI, HESS, and ATIC data on electron spectra in the 1-TeV range and more accurate data on cosmic ray (CR) proton anisotropy, since only nearby sources determine the anisotropy value and electron intensity in the 1 TeV range. The experimental procedure for measuring proton anisotropy is reproduced in our calculations for the first time. The time dependence of radiation and the arm structure of the Galaxy are taken into account. Some variants of our calculations are given that allow the simultaneous description of the experimental energy dependences of the amplitude and phase of anisotropy and electron spectra. An estimate of the possible contribution of electron-positron emission from pulsar magnetospheres is given as well.
