 | Sokolsky, Pierre | First observation of the Greisen-Zatsepin-Kuzmin suppression | The High Resolution Fly's Eye (HiRes) experiment has observed the Greisen-Zatsepin-Kuzmin suppression (called the GZK cutoff) with a statistical significance of five standard deviations. HiRes' measurement of the flux of ultrahigh energy cosmic rays shows a sharp suppression at an energy of 6 x 10^1... | Extensive air showers; Suppression; Energy spectrum; Fluorescence; GZK cutoff | 2008-03 |

 | Sokolsky, Pierre | Highest energy cosmic rays and results from the HiRes experiment | The status of the field of ultrahigh energy cosmic ray physics is summarized, from the point of view of the latest results of the High Resolution Fly's Eye (HiRes) Experiment. HiRes results are presented, and compared with those of the Akeno Giant Air Shower Array (AGASA), plus the Telescope Array ... | Fluorescence; Energy spectrum; GZK cutoff; Extensive air showers; Anisotropy | 2007-11-01 |

 | Sokolsky, Pierre | Highest-energy cosmic rays | What in the cosmos can possibly be accelerating protons to 1020 electron volts and beyond? And how can they preserve such extreme energies while plowing through the cosmic microwave background on their way to us? | Energy spectrum; GZK cutoff; Atmospheric fluorescence | 1998 |

 | Sokolsky, Pierre | Measurement of the flux of ultra high energy cosmic rays by the stereo technique | The High Resolution Fly's Eye (HiRes) experiment has measured the flux of ultrahigh energy cosmic rays using the stereoscopic air fluorescence technique. The HiRes experiment consists of two detectors that observe cosmic ray showers via the fluorescence light they emit. HiRes data can be analyzed i... | Ultrahigh energy cosmic rays; Fluorescence; Energy spectrum; GZK cutoff | 2009-08 |
