Search of the paired events in cosmic rays with energy above 5 EeV in Yakutsk EAS array data
2019 July 22
The highest energy extensive air showers that come one after the other in a narrow time interval and have similar galactic coordinates are analyzed. There is no significant excess in overall statistics of paired events over the random distribution. Next, the showers with the difference in arrival time up to five hours, and the difference of galactic coordinates less than 10 degrees were selected for analysis from Yakutsk EAS Array data. We found that such paired EAS events have an approximately the same characteristics: energy and the content of muons.
