Abstract content

The arrival directions of ultrahigh energy extensive air showers registered at the Yakutsk array are considered. The correlations of maxima in the distribution of arrival directions of showers and doublets with the pulsar coordinates located in the galactic plane are found. It is shown that the correlation of the arrival directions of ultrahigh energy particles with the plane of Virgo cluster is caused by the particles which arrive from the side of pulsars located on the intersection of planes of the Galaxy and the Virgo clusters.
