Kieda, David B.; Gaisser, Thomas K.; Sokolsky, Pierre | Cosmic-ray composition around 10^18 eV | We use the depth of maximum distribution as measured by the stereo Fly's Eye detector to study the chemical composition of the primary cosmic radiation between 3x 1017 eV and 1019 eV. The analysis depends on the use of simulations to study the response of the detector as well as sensitivity to assum... | Fly's Eye; Cosmic ray composition; Cosmic ray nuclei; Chemical composition | 1993-03 |

Kieda, David B.; Gaisser, Thomas K.; Sokolsky, Pierre | Evidence for correlated changes in the spectrum and composition of cosmic rays at extremely high energies | The Utah Fly's Eye detector has revealed a change in the cosmic ray composition which is correlated with structure in the all-particle energy spectrum. The data can be fitted by a simple model of a steep power law spectrum of heavy nuclei which is overtaken at high energies by a flatter spectrum o... | Ultrahigh energy cosmic rays; Fly's Eye; Cosmic ray composition; Cosmic ray spectrum | 1993-11 |

Kieda, David B.; Cassiday, George L.; Sokolsky, Pierre | Search for γ rays above 1014 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 ... | Fly's Eye | 1989-11 |
