标题： Ground-Based Gamma-Ray Astronomy at Energies Above 10 TeV: Searching for Galactic PeV Cosmic-Ray Accelerators

摘要： 银河宇宙射线在“膝区”能量以上的起源仍未被解答，并且强烈促使人们去研究10 TeV以上能量的伽马射线源。 我们讨论了基于地面的切伦科夫成像系统在这些能量上的近期成果以及该方向未来的观测努力。 H.E.S.S.令人兴奋的结果提供了关于银河宇宙射线加速器性质的一些线索，并表明存在一类银河伽马射线源，其辐射延伸至超过10 TeV。 一个针对更高能量优化的切伦科夫成像望远镜专用系统似乎是研究多TeV伽马射线天空的一种有前景的方式。 显示英文摘要

摘要： The origin of Galactic CRs up the knee energy remains unanswered and provides strong motivation for the study of gamma-ray sources at energies above 10 TeV. We discuss recent results from ground-based gamma-ray Cherenkov imaging systems at these energies as well as future observational efforts in this direction. The exciting results of H.E.S.S. give clues as to the nature of Galactic CR accelerators, and suggest that there is a population of Galactic gamma-ray sources with emission extending beyond 10 TeV. A dedicated system of Cherenkov imaging telescopes optimised for higher energies appears to be a promising way to study the multi-TeV gamma-ray sky.
