Cosmic rays beyond the knees

Nature volume 531, pages 43–44 (2016)Cite this article

Subjects

The development of a radio technique for detecting cosmic rays casts fresh light on the origins of some of these accelerated particles, and suggests that they might have travelled much farther than was previously thought. See Letter p.70

A technique for measuring the composition of cosmic rays in the energy range 1017 to 1017 electronvolts — a range thought to mark the transition point from Galactic to extragalactic cosmic rays — is reported by Buitink et al.1 on page 70 of this issue. The findings have implications for our understanding of the sources of these mysterious rays.
