高能天体物理学的跨学科问题
Interdisciplinary Aspects of High-Energy Astrophysics
摘要：
现代天体物理学，特别是在GeV能量尺度及以上，是几个学科交汇的典型例子：源的位置和分布是天文学的领域。在对应于显着红移的距离处，宇宙学方面（例如膨胀历史）开始发挥作用。最后，产生的高能粒子的发射机制和随后的传播至少部分是粒子物理学的领域，特别是如果探测到标准模型之外的新现象，需要实验室中无法获得的基线和/或能量。在这篇文章中，我们集中在三个例子：最高能量的宇宙射线，洛伦兹对称性的测试和寻找新的轻光子在活动星系的光谱状态。
英文摘要：
Modern astrophysics, especially at GeV energy scales and above is a typical example where several disciplines meet: The location and distribution of the sources is the domain of astronomy. At distances corresponding to significant redshift cosmological aspects such as the expansion history come into play. Finally, the emission mechanisms and subsequent propagation of produced high energy particles is at least partly the domain of particle physics, in particular if new phenomena beyond the Standard Model are probed that require base lines and/or energies unattained in the laboratory. In this contribution we focus on three examples: Highest energy cosmic rays, tests of the Lorentz symmetry and the search for new light photon-like states in the spectra of active galaxies.
