Cosmic rays from the ankle to the cutoff
[Les rayons cosmiques, de la cheville à la coupure]
Comptes Rendus. Physique, Volume 15 (2014) no. 4, pp. 318-328.

Les récentes avancées des mesures et de l'interprétation des rayons cosmiques, depuis la caractéristique spectrale appelé « cheville » jusqu'aux plus hautes énergies, sont brièvement revues. Aux plus hautes énergie, la question principale concerne l'origine de la suppression du flux observée au dessus de 41019 eV. Est-ce la prédiction GZK tant attendue, ou bien l'épuisement des sources ? La réponse à cette question sera fournie par la mesure de la composition des rayons cosmiques aux plus hautes énergies, qui est aujourd'hui largement inconnue. L'isotropie des directions d'arrivée observées même aux plus hautes énergies défavorise les modèles où les protons dominent la composition, si les champs magnétiques extragalactiques sont au plus de quelques nG. Nous discuterons les progrès expérimentaux et théoriques du domaine et les perspectives pour la prochaine décennie.

Recent advances in measuring and interpreting cosmic rays from the spectral ankle to the highest energies are briefly reviewed. The prime question at the highest energies is about the origin of the flux suppression observed at E41019 eV. Is this the long-awaited GZK-effect or the exhaustion of sources? The key to answering this question will be provided by the largely unknown mass composition at the highest energies. The high level of isotropy observed even at the highest energies challenges models of a proton-dominated composition if extragalactic magnetic fields are on the order of a few nG or less. We shall discuss the experimental and theoretical progress in the field and the prospects for the next decade.
