摘要

Data from the Yakutsk extensive air shower array for the period 1974-2004 are used to analyze the energy spectrum and anisotropy of primary cosmic rays (PCRs) with energy E-0 >= 10(17) eV. The spectra from different regions of the sky are shown to differ in shape. Enhanced and reduced particle fluxes come from the disks of the Galaxy and the Supergalaxy (the Local Supercluster of galaxies) at E-0 >= 5 x 10(18) eV and E-0 <= (2-3) x 10(18) eV, respectively. This is interpreted as a manifestation of the possible interaction between extragalactic PCRs and the matter of these spatial structures. (c) 2005 Pleiades Publishing, Inc.
