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.

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) experienced by cosmic rays during propagation in the Galaxy.

Cosmic neutrino pevatrons: A brand new pathway to astronomy, astrophysics, and particle physics

TL;DR: In this article, 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 physical processes which may either explain or be constrained by IceCube data.

Cosmic ray spectrum and anisotropies from the knee to the second knee

TL;DR: In this article, the authors consider the scenario in which the knee in the cosmic ray spectrum is due to a change in the escape mechanism of cosmic rays from the Galaxy from one dominated by transverse diffusion to one dominating by drifts and show that this scenario explains not only the changes in spectral slope at the knee and at the second knee, but can also account for the main characteristics of the observed energy-dependent anisotropy amplitude and phase of first harmonic in the energy range between 1015 and 1018 eV.
