Cosmic Rays from the Knee to the Highest Energies

4 Apr 2009 · J. Bluemer, R. Engel, J. R. Hoerandel ·

This review summarizes recent developments in the understanding of high-energy cosmic rays. It focuses on galactic and presumably extragalactic particles in the energy range from the knee (10^15 eV) up to the highest energies observed (>10^20 eV). Emphasis is put on observational results, their interpretation, and the global picture of cosmic rays that has emerged during the last decade.
