标题： Particle Acceleration and Cosmic-Ray Origin in the Galaxy

摘要： 20世纪90年代，甚高能伽马射线天文学因切伦科夫望远镜（IACTs）的发展取得了显著进展。自1989年首次探测到来自蟹状星云的TeV伽马射线辐射后，几种类型的TeV伽马射线源被发现，包括活动星系核（AGN）、年轻脉冲星和超新星遗迹（SNR）。在这些发现中，来自几个超新星遗迹的同步辐射X射线和TeV伽马射线辐射的最近探测尤为重要。超新星遗迹一直被认为是银河宇宙射线起源的独特候选者，自从宇宙射线物理学开始以来就如此，但到目前为止，观测证据仍然很少。这些发现不仅有望成为银河宇宙射线起源的线索，还可能有助于理解由于扩散冲击而导致的粒子加速过程。在这里，我介绍了我们小组CANGAROO关于超新星遗迹中电子和质子加速证据的最新研究成果。 显示英文摘要

摘要： In 1990's Very High Energy Gamma-ray Astrophysics has dramatically advanced due to the Imaging Air \v{C}erenkov Telescopes(IACTs). After the first detection of TeV gamma-ray emission from the Crab nebula in 1989, several type of TeV gamma-ray sources, Active Galactic Nuclei(AGN), young pulsar, and SuperNova Remnant(SNR), have been detected. In those discoveries, recent detections of both synchrotron X-rays and TeV gamma-ray emissions from several SNRs are very significant. SNR has been widely believed to be an unique candidate of galactic cosmic-ray origin since the beginning of cosmic-ray physics, whereas little observational evidences have been reported so far. Those are expected to be a clue of not only the galactic cosmic-ray origin but also the understanding of the particle acceleration due to a diffusive shock. Here I present the recent results obtained by our group, CANGAROO, about the evidences of electron and proton acceleration in SNRs.
