Abstract

The origin of the most energetic particles ever observed, cosmic rays, will begin to be revealed in the next few years. Newly constructed ultrahigh-energy cosmic ray observatories together with high-energy gamma-ray and neutrino observatories are well positioned to unveil this mystery before the centenary of their discovery in 2012. Cosmic ray sources are likely to involve the most energetic phenomena ever witnessed in the universe.

摘要

有史以来观测到的能量最高的粒子——宇宙射线的起源，将在未来几年开始揭开面纱。新建成的超高能宇宙射线天文台，连同高能伽马射线和中微子天文台，有能力在2012年宇宙射线发现一百周年之前解开这个谜团。宇宙射线源很可能涉及宇宙中曾见证过的最具能量的现象。
