| Abstract: | We present the results of analyzing the arrival directions of cosmic rays with energies E 0≥ 4×1017 eV and zenith angles θ≤45° detected at the Yakutsk setup during 1974–2000. It is shown that increased particle fluxes exceeding the anticipated random distribution levels by 4–5)σ arrive from the galactic plane at E 0≈(2–4)×1018 eV and from the supergalactic plane at E 0≥8×1018 eV. |
