在过去十年该领域的戏剧性发展中，德国的团体和机构在高能天体物理学中发挥了核心的、往往是决定性的作用。伽马射线源的空间分辨率和时间研究都以前所未有的灵敏度进行，破译了银河系和河外高能发射源的物理过程，并为基础物理提供了新的见解。对致密天体，特别是黑洞和中子星的射电观测，可以在极端条件下探索物理，并测试基本性质，如黑洞周围是否存在事件视界。对超高能宇宙射线的观测提供了关于最高能量下粒子加速的信息。2013年首次探测到宇宙高能中微子，被评为本年度物理学世界的突破。
During a dramatic development of the field over the last decade, German groups and institutions have played central, often decisive, roles in high-energy astrophysics. Both spatially resolved and temporal studies of gamma-ray sources are conducted with unprecedented sensitivity, deciphering the physical processes in Galactic and extragalactic sources of high-energy emission, and providing new insights into fundamental physics. Radio observations of compact objects, especially black holes and neutron stars, permit exploring physics under extreme conditions and testing for fundamental properties such as the existence of event horizons around black holes. Observations of ultra-high energy cosmic rays provide information on particle acceleration at the highest energy. The first detection in 2013 of cosmic high-energy neutrinos was named the Physics World breakthrough of the year.
