论文摘要
宇宙中最强大的持久加速器是喷射的活跃星系。射流的星系，其喷气机朝向地球，主导了乳突外伽马射线的天空。尽管如此，大多数最高能量的粒子加速器可能会避免检测。这些极端的辐射能量可以超过10 TEV的峰值，是研究颗粒加速和辐射过程的理想目标，并可能提供与宇宙射线和天体物理中微子的联系。在TEV能量上观察到的极端地球的数量越来越重要，对于伽马射线宇宙学的出现至关重要，包括测量了阿拉加层次的背景光，在层状磁场上的紧密界限，以及对人类制作的加速器无法获得的能量的外来物理学的限制。在过去的十年中，取得了巨大的进步，这对未来造成了很好的影响，尤其是随着切伦科夫望远镜阵列的部署。
The most powerful persistent accelerators in the Universe are jetted active galaxies. Blazars, galaxies whose jets are directed towards Earth, dominate the extragalactic gamma-ray sky. Still, most of the highest-energy particle accelerators likely elude detection. These extreme blazars, whose radiated energy can peak beyond 10 TeV, are ideal targets to study particle acceleration and radiative processes, and may provide links to cosmic rays and astrophysical neutrinos. The growing number of extreme blazars observed at TeV energies has been critical for the emergence of gamma-ray cosmology, including measurements of the extragalactic background light, tight bounds on the intergalactic magnetic field, and constraints on exotic physics at energies inaccessible with human-made accelerators. Tremendous progress has been achieved over the past decade, which bodes well for the future, particularly with the deployment of the Cherenkov Telescope Array.
