Energy spectra of cosmic-ray nuclei at high energies
H. S. Ahn, P. Allison, M. G. Bagliesi +30
We present new measurements of the energy spectra of cosmic-ray (CR) nuclei from the second flight of the balloon-borne experiment Cosmic Ray Energetics And Mass (CREAM). The instr…
Upper limit on the cosmic-ray photon fraction at EeV energies from the Pierre Auger Observatory
The Pierre Auger Collaboration, J. Abraham, P. Abreu +458
From direct observations of the longitudinal development of ultra-high energy air showers performed with the Pierre Auger Observatory, upper limits of 3.8%, 2.4%, 3.5% and 11.7% (a…
IceRay: An IceCube-centered Radio-Cherenkov GZK Neutrino Detector
P. Allison, J. Beatty, P. Chen +18
We discuss design considerations and simulation results for IceRay, a proposed large-scale ultra-high energy (UHE) neutrino detector at the South Pole. The array is designed to det…
