 | Sokolsky, Pierre; Cassiday, George L.; Kieda, David B. | Search for y rays above 10^14 eV from Cygnus X-3 during the June and July 1989 radio outbursts | We have looked for γ-ray emission above 100 TeV from the binary x-ray source Cygnus X-3 during a period of intense radio emission in the summer of 1989. We find no evidence for excess air showers from the direction of the source and the muon content of air showers from this direction is the same as... | Cygnus X-3; Radio outbursts; Extensive air showers | 1989-11 |

 | Sokolsky, Pierre | Evidence for 10^18-eV neutral particles from the direction of Cygnus X-3 | 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 i... | Cygnus X-3; Extensive air showers; Neutral particles | 1989-01 |

 | Sokolsky, Pierre | Search for compact sources of cosmic photons above 200 TeV | From April 1988 to February 1990 we used a two-level array of scintillators to search in the cosmic radiation for compact sources of y rays above 200 TeV. Counters on the surface measured the size and direction of extensive air showers while counters buried 3 m below ground measured their muon conte... | Extensive air showers; Cygnus X-3; Hercules X-1; Crab Nebula; Ultrahigh energies | 1992-10 |

 | Sokolsky, Pierre | Search for > 200 TeV photons from Cygnus X-3 in 1988 and 1989 | Over a period of 16 months from April 1988 to August 1989, we have monitored the flux of cosmic-ray showers with energies above 2X 10^14 eV. We used a two-level array of scintillators covering an area of 3 X 10^4 m2 . Counters on the surface measure the size and direction of each shower while counte... | Cygnus X-3; Extensive air showers | 1990-07 |

 | Kieda, David B. | High statistics search for ultrahigh energy gamma-ray emission from Cygnus X-3 and Hercules X-1 | We have carried out a high statistics (2 X 10 9 events) search for ultrahigh energy g-ray emission from the x-ray binary sources Cygnus X-3 and Hercules X-1. Using data taken with the CASA-MIA detector over a five year period (1990-1995), we find no evidence for steady emission from either source. T... | Cygnus X-3; Hercules X-1; Ultrahigh energy; X-rays | 1997 |
