The presence of a large-scale anisotropy in the cosmic radiation has been known for several decades. Earlier experiments lacked the statistical power to observe small-scale anisotropies in the cosmic radiation and there were good reasons to expect that on small scales the cosmic radiation would be smooth. The Milagro extensive air shower array discovered the presence of at least two small...
7. The cosmic ray anisotropy measured by the ARGO-YBJ experiment and the status of the LHASSO project
Dr Songzhan Chen (Institute of High Energy Physics (IHEP))
The ARGO-YBJ experiment is located at Yang Ba Jing (P.R. China), at 4300 m a.s.l. and atmospheric depth of 606 g/cm^2. It is an air shower detector array with a fully covered layer of Resistive Plate Chambers. It is designed to detect EAS in the primary energy range between few hundred GeV and a few PeV. It has been continuously operated with a duty cycle above 86% since November 2007...

The ARGO-YBJ experiment, located at the Yangbajing Cosmic Ray Laboratory (Tibet, 4300 m asl, 606 g/cm2), is an EAS-array exploiting the full coverage approach at high altitude. We analyzed the data taken since November 2007 looking for anisotropies in the arrival directions of cosmic rays on different angular scales. The results of the analysis are reported and compared with other experiments.

The IceCube Neutrino Observatory, located at the geographic South Pole, employs a km3 of Antarctic ice as a particle detector to search for sources of astrophysical neutrinos across the southern sky. The high rate of CR events in the detector has allowed to search for anisotropy in this data sample at the per-mille level. I'll report on the observation of CR anisotropy in the 20 TeV...
