Abbasi R, Abe Y, Abu-Zayyad T, Allen M, Arai Y, Arimura R, et al.
Phys Rev Lett . 2024 Aug; 133(4):041001. PMID: 39121414
We report an estimation of the injected mass composition of ultrahigh energy cosmic rays (UHECRs) at energies higher than 10 EeV. The composition is inferred from an energy-dependent sky distribution...

Abbasi R, Allen M, Arimura R, Belz J, Bergman D, Blake S, et al.
Science . 2023 Nov; 382(6673):903-907. PMID: 37995237
Cosmic rays are energetic charged particles from extraterrestrial sources, with the highest-energy events thought to come from extragalactic sources. Their arrival is infrequent, so detection requires instruments with large collecting...

Abbasi R, Abu-Zayyad T, Al-Seady M, Allen M, Amman J, Anderson R, et al.
Phys Rev Lett . 2010 May; 104(16):161101. PMID: 20482038
We report studies of ultrahigh-energy cosmic-ray composition via analysis of depth of air shower maximum (X(max)), for air shower events collected by the High-Resolution Fly's Eye (HiRes) observatory. The HiRes...

Abbasi R, Abu-Zayyad T, Allen M, Amman J, Archbold G, Belov K, et al.
Phys Rev Lett . 2008 Mar; 100(10):101101. PMID: 18352170
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...

Abbasi R, Abu-Zayyad T, Amann J, Archbold G, Bellido J, Belov K, et al.
Phys Rev Lett . 2004 Jun; 92(15):151101. PMID: 15169276
We have measured the cosmic ray spectrum above 10(17.2) eV using the two air-fluorescence detectors of the High Resolution Fly's Eye observatory operating in monocular mode. We describe the detector,...
