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.

Cosmic Neutrino Pevatrons: A Brand New Pathway to Astronomy, Astrophysics, and Particle Physics

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.

Diffusive propagation of cosmic rays from supernova remnants in the Galaxy. II: anisotropy

TL;DR: In this article, the effects of stochasticity in the spatial and temporal distribution of supernova remnants on the anisotropy of cosmic rays observed at Earth were investigated for different choices of the diffusion coefficient D(E) for propagation in the Galaxy.

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.

Search for first harmonic modulation in the right ascension distribution of cosmic rays detected at the Pierre Auger Observatory

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.
