This review summarizes recent developments in the understanding of high-energy cosmic
rays. It focuses on galactic and presumably extragalactic particles in the energy range from …

The search for the origin of cosmic rays with energies above 1018 eV has made
considerable progress during the past few years. With new data from the High Resolution …

Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival
directions of the cosmic rays with the highest-energies, which are correlated with the …

We study the feasibility of a new generation axion helioscope, the most ambitious and
promising detector of solar axions to date. We show that large improvements in magnetic …

We present the results of time-integrated searches for astrophysical neutrino sources in both
the northern and southern skies. Data were collected using the partially completed IceCube …

A method is developed to search for air showers initiated by photons using data recorded by
the surface detector of the Auger Observatory. The approach is based on observables …

ABSTRACT Between 2009 May and 2010 May, the IceCube neutrino detector at the South
Pole recorded 32 billion muons generated in air showers produced by cosmic rays with a …

We present the results of the search for ultra-high-energy photons with nine years of data
from the Telescope Array surface detector. A multivariate classifier is built upon 16 …

We present the results of searches for high-energy muon neutrinos from 41 gamma-ray
bursts (GRBs) in the northern sky with the IceCube detector in its 22 string configuration …

We study the anisotropy of Ultra-High Energy Cosmic Ray (UHECR) events collected by the
Telescope Array (TA) detector in the first 40 months of operation. Following earlier studies …
