Cosmic rays are hampered by the Moon and a deficit in its direction is expected (the so-called \emph{Moon shadow}). The Moon shadow is an important tool to determine the performance of an air shower a...
Search for Nuclei Sources in the Ultra-High Energy Cosmic Ray Data
Ultra-High Energy Cosmic Rays Galactic Magnetic Field
2011/10/8
We present a new method to search for heavy nuclei sources, on top of background, in the Ultra-High Energy Cosmic Ray data. We apply it to the 69 events with energies E>55 EeV published by the Pierre ...

We propose a new way to detect individual bright Ultra-High Energy Cosmic Ray (UHECR) sources above background if the Galactic Magnetic Field (GMF) gives the main contribution to UHECR deflections. Th...
IceCube as a three-dimensional air-shower array covers an energy range of the cosmic-ray spectrum from below 1 PeV to approximately 1 EeV. This talk is a brief review of the function and goals of IceT...
Semi-analytical model of cosmic ray electron transport
Semi-analytical model cosmic ray electron transport
2011/9/28
We present a numerical extension to the analytical propagation model introduced in Hein and Spanier (2008) to describe the leptonic population in the galactic disc. The model is used to derive a possi...
A heliospheric hybrid model：hydrodynamic plasma flow and kinetic cosmic ray transport
heliospheric hybrid hydrodynamic plasma flow kinetic cosmic ray transport
2009/5/27
In this paper we present a new five particle species hybrid model for calculating cosmic ray particle transport and acceleration in a dynamic heliospheric environment. In particular the effects of sol...
Forbush decrease of the galactic cosmic ray intensity：experimental study and theoretical modeling
cosmic ray intensity theoretical modeling
2009/5/27
We study the temporal changes of the power law rigidity spectrum of the Forbush decrease (Fd) of the galactic cosmic ray (GCR) intensity. We show that the power law rigidity spectrum of Fd for the pe...
27-day variations of the galactic cosmic ray intensity and anisotropy
cosmic ray intensity 27-day variations
2009/5/27
We study the 27-day variations of the galactic cosmic ray (GCR) intensity and three dimensional (3-D) anisotropy in different polarity periods of the solar magnetic cycle. We found that the larger am...

The average characteristics of the diurnal and semi-diurnal
anisotropy of cosmic ray intensity at relativistic energies have been obtained
by using data from the worldwide grid of neutron monitor fo...
Long-term Modulation of Cosmic Ray Intensity in relation to Sunspot Numbers and Tilt Angle
Cosmic ray intensity sunspot numbers tilt angle
2009/5/7
Adetailed correlative analysis between sunspot numbers (SSN) and tilt angle (TA) with cosmic ray intensity (CRI) in the neutron monitor energy range has been performed for the solar cycles 21, 22 and ...
