Abstract
The role pulsar wind nebulae play in producing our locally observed cosmic ray spectrum remains murky, yet intriguing. Pulsar wind nebulae are born and evolve in conjunction with SNRs, which are favored sites of Galactic cosmic ray acceleration. As a result they frequently complicate interpretation of the gamma-ray emission seen from SNRs. However, pulsar wind nebulae may also contribute directly to the local cosmic ray spectrum, particularly the leptonic component. This paper reviews the current thinking on pulsar wind nebulae and their connection to cosmic ray production from an observational perspective. It also considers how both future technologies and new ways of analyzing existing data can help us to better address the relevant theoretical questions. A number of key points will be illustrated with recent results from the VHE (E > 100 GeV) gamma-ray observatory VERITAS.
脉冲星风星云在产生我们局部观测到的宇宙射线光谱中所扮演的角色仍然很模糊，但很有趣。脉冲星风星云与信噪比一起诞生和演化，信噪比是银河系宇宙射线加速的有利地点。因此，它们经常使从信噪比观测到的伽马射线发射的解释复杂化。然而，脉冲星风星云也可能直接对局部宇宙射线谱做出贡献，特别是轻子成分。本文从观测的角度综述了目前关于脉冲星风星云及其与宇宙射线产生的联系的观点。它还考虑了未来的技术和分析现有数据的新方法如何帮助我们更好地解决相关的理论问题。一些关键点将用VHE (E >100 GeV)伽马射线天文台VERITAS。
