Large‐Scale Cosmic‐Ray Anisotropy with KASCADE

Abstract

The results of an analysis of the large scale anisotropy of cosmic rays in\nthe PeV range are presented. The Rayleigh formalism is applied to the right\nascension distribution of extensive air showers measured by the KASCADE\nexperiment.The data set contains about 10^8 extensive air showers in the energy\nrange from 0.7 to 6 PeV. No hints for anisotropy are visible in the right\nascension distributions in this energy range. This accounts for all showers as\nwell as for subsets containing showers induced by predominantly light\nrespectively heavy primary particles. Upper flux limits for Rayleigh amplitudes\nare determined to be between 10^-3 at 0.7 PeV and 10^-2 at 6 PeV primary\nenergy.\n
