TLDR
In this article, the results of an analysis of the large-scale anisotropy of cosmic rays in the PeV range were presented, and the Rayleigh formalism was applied to the right ascension distribution of extensive air showers measured by the KASCADE (Karlsruhe Shower Core and Array Detector) experiment.Abstract:
We present the results of an analysis of the large-scale anisotropy of cosmic rays in the PeV range. The Rayleigh formalism is applied to the right ascension distribution of extensive air showers measured by the KASCADE (Karlsruhe Shower Core and Array Detector) experiment. The data set contains about 108 extensive air showers in the energy range 0.7-6 PeV. No hints of anisotropy are visible in the right ascension distributions in this energy range. This accounts for all showers, as well as for subsets containing showers induced by predominantly light or heavy primary particles, respectively. Upper flux limits for Rayleigh amplitudes are determined to be between 10-3 at a primary energy of 0.7 PeV and 10-2 at 6 PeV.read more

TL;DR: In this paper, the authors review the many possibilities which have been explored in the literature to address this question, including origins at either Galactic or extragalactic celestial objects, and briefly discuss new physics processes which may either explain or be constrained by IceCube data.

TL;DR: The amplitude and phase of the cosmic-ray anisotropy were well established experimentally between 1011 eV and 1014 eV, and the study of their evolution in the energy region 1014-1016 eV can provide a significant tool for the understanding of the steepening ("knee") of the primary spectrum.

The anisotropy of galactic cosmic rays as a product of stochastic supernova explosions
TL;DR: In this paper, the effect of supernova explosions on the anisotropy of galactic cosmic rays below the knee was studied, and it was shown that if the bulk of cosmic rays are produced in supernova explosion, the observed small and nearly energy independent amplitude of the cosmic rays and its phase are to the large extent determined by the history of these explosions in the vicinity of the solar system, namely by the location and the age of the supernova remnants, within a few kpc, which give the highest contribution to the total intensity at the present epoch.

TL;DR: In this article, the results of searches for dipolar-type anisotropies in different energy ranges above 2.5 x 10(17) eV with the surface detector array of the Pierre Auger Observatory were reported on both the phase and amplitude measurements of the first harmonic modulation in the right-ascension distribution.

CORSIKA: A Monte Carlo code to simulate extensive air showers
TL;DR: In this paper, the evolution of the information seeking and use models for professionals, essentially, the information access practices, is discussed. But two main categories can be distinguished : the informationseeking and use model versus the information retrieval model, and we will evaluate them in order to see if a convergence is possible with the same vocabulary and procedures.

Quark-Gluon String Model and EAS Simulation Problems at Ultra-High Energies
TL;DR: The reliability of model calculations is of considerable significance because at energies above those attained by accelerators only model predictions enable us to extract primary cosmic ray characteristics as discussed by the authors, which is of particular relevance in the case of EAS simulations.
