Title Evidence for 10^18-eV neutral particles from the direction of Cygnus X-3
Date 1989-01
Description Analysis of the cumulative Fly's Eye data reveals an excess of air showers from the direction of Cygnus X-3 at energies above 0.5 x 10^18 eV. No point source has previously been identified at such high energies. The probability of this excess arising as a chance clustering of isotropic cosmic rays is 6 . 5 x 10^-4 . The inferred signal flux is (2.0 ± 0.6) x 10&-17 particles/cm2 s. The Cygnus X-3 4.8-h periodicity is weakly present in the data.
