Large-Scale Cosmic-Ray Anisotropy with KASCADE

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.

Signatures of the transition from galactic to extragalactic cosmic rays

TL;DR: In this article, the authors discuss the signatures of the transition from galactic to extragalactic cosmic rays in different scenarios, giving the most attention to the dip scenario, which is caused by electron-positron pair production on the cosmic microwave background radiation.

Excesses of Cosmic Ray Spectra from A Single Nearby Source

TL;DR: In this paper, a nearby supernova remnant surrounded by a giant molecular cloud is assumed to be the source of the anomalous cosmic ray spectra, and it is shown that the TeV to sub-PeV anisotropy of the proton is consistent with the observations if the local source is relatively young and lying at the anti-Galactic center direction.

Origin of Small-Scale Anisotropies in Galactic Cosmic Rays

TL;DR: In this paper, a review of the current experimental situation for both the large-scale and small-scale anisotropies is presented, where the authors address some of the issues in comparing different experimental results and remaining questions in interpreting the observed large scale anisotropic signals.

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.
