Search for cosmic-ray anisotropy with KASCADE

An analysis of arrival directions of about 150 Mio. extensive air showers (EAS) in the primary energy range between 0.3 and 300 PeV measured by the KASCADE experiment is presented in this work. A new arrival direction reconstruction method using the arrival times of the shower particles in the detectors and the number of particle in the detector has been tested and integrated in the standard framework of the KASCADE reconstruction. No hints for large scale anisotropy were found in an harmonic analysis of the right ascensions of the EAS. An upper limit of about 10-3 bis 10-2 for amplitudes of the first harmonic were found using the Rayleigh formalism. A point source search, including a sky survey (15 < δ < 85 ) and a dedicated search at the site of selected point source candidates (supernovae, pulsars, the galactic plane, TeV-γ sources,..) resulted in an upper limit for point sources of about 10-9-10-10 m-2 s-1 at an energy threshold of 350 TeV. Inspecting the arrival directions of EAS with energies above 80 PeV by an autocorrelation analysis yield as well no hints for any clustering of these EAS in the KASCADE data. (orig.)
