Description
The detection of high-energy cosmic rays above a few hundred TeV is realized by the
observation of extensive air-showers. By using the multi-detector setup of
KASCADE-Grande the energy spectrum, elemental composition, and anisotropies of
high-energy cosmic rays in the energy range from below the knee up to 1 EeV are
investigated. The most distinct feature of the spectrum, the ‘knee’, is thought to be
the beginning of the end of the galactic origin of cosmic rays. As the highest
energies (above the ‘ankle’) are most probably of extragalactic origin, between 10
PeV to 1 EeV one expects the transition of galactic to extragalactic origin.
KASCADE-Grande is dedicated to explore this transition region. The estimation of
energy and mass of the high-energy primary particles is based on the combined
investigation of the charged particle, the electron, and the muon components measured
by the detector arrays of Grande and KASCADE. Recent results from the KASCADE-Grande
experiment will be shown and compared with results from other experiments, and their
astrophysical implications discussed.
