Observation of the Cosmic Ray Moon shadowing effect with the ARGO-YBJ experiment
Extensive Air Showers, Cosmic Rays, Moon shadow, Geomagnetic fi eld, ARGO-YBJ
2011/10/10
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 ...

2011/10/8
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...
Gamma-Ray Constraints on Maximum Cosmogenic Neutrino Fluxes and UHECR Source Evolution Models
Gamma-Ray Constraints Cosmogenic Neutrino Fluxes Source Evolution Models
2011/9/29
The dip model assumes that the ultra-high energy cosmic rays (UHECRs) above 10$^{18}$ eV consist exclusively of protons and is consistent with the spectrum and composition measure by HiRes. Here we pr...
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...
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 ...
