Cosmic Rays (Theory/Experiment) Parallel
The study of the cosmic ray anisotropy in the TeV-PeV energy range could provide clues about the
origin and propagation of cosmic rays in our galaxy. The measurement of this per-mille-anisotropy
requires data sets with several billion cosmic-ray events. A sample of this size has been collected
over the last six years by the IceCube neutrino telescope at the south pole, which detects...

Cosmic Rays (Theory/Experiment) Parallel
The ARGO-YBJ experiment consists of a 5700 m2 single layer of Resistive
Plate Chambers situated at the Yangbajing Cosmic Ray Laboratory, Tibet (P.R. of China), 4300
meters a.s.l. A partially instrumented guard ring (1700 m2) around the
central zone extends the instrumented area up to 11000 m2.
The experiment is sensitive to extensive air showers initiated by
primaries in the 10^9-10^15 eV...

Cosmic Rays (Theory/Experiment) Parallel
The flux and nuclear composition of ultra-high energy cosmic rays depend on the cosmic distribution of their sources. Data from cosmic ray observatories are yet inconclusive about their exact location or distribution, but provide a measure for the average local density of these emitters. Due to the discreteness of the emitters the flux and nuclear composition is expected to show ensemble...

Cosmic Rays (Theory/Experiment) Parallel
The Galactic magnetic deflection of cosmic rays from a source strongly depends on the Galactic magnetic field (GMF) model. We use the recent GMF model of Jansson and Farrar (JF12), a 35-parameter model which includes coherent, striated and random components and is constrained by WMAP synchrotron maps and all available extragalactic rotation measures. Here, we present the results of propagating...

Cosmic Rays (Theory/Experiment) Parallel
Particles can be accelerated to above 10**19 eV by newborn pulsars with spin period less than 10 millisecond. These cosmic rays travel through the dense stellar remnant surrounding the pulsar, and then reach the earth. With the appropriate injection composition, ultrahigh energy cosmic rays from extragalactic pulsars can fit both the energy spectrum and composition (Xmax and RMS-Xmax) measured...
