检查河外gamma-ray源光谱中的吸收以洞察洛伦兹不变性破坏
Inspecting absorption in the spectra of extra-galactic gamma-ray sources for insight into Lorentz invariance violation
摘要：
我们研究了银河系外TeV伽马射线源，如耀变体，在洛伦兹不变性破坏（LIV）的存在下，吸收光谱会是什么样子。对生产与河外背景光修改观察到的光谱，这样的来源，我们表明，违反洛伦兹不变性一般会有一个戏剧性的影响，这种吸收功能。检查这种效应，一个实验性的任务可能在不久的将来实用，可以提供独特的洞察力的可能性LIV。
英文摘要：
We examine what the absorbed spectra of extra-galactic TeV gamma-ray sources, such as blazars, would look like in the presence of Lorentz invariance violation (LIV). Pair-production with the extra-galactic background light modifies the observed spectra of such sources, and we show that a violation of Lorentz invariance would generically have a dramatic effect on this absorption feature. Inspecting this effect, an experimental task likely practical in the near future, can provide unique insight on the possibility of LIV.
