第一 摘要（1）：Gamma-ray observations provide important information on cosmic-ray (CR) propagation in our Galaxy. First, we discuss TeV halos. We show that current gamma-ray measurements place interesting constraints on the turbulent magnetic fields around these pulsars, and we examine the implications for CR transport. Also, we suggest that extended gamma-ray sources of a hadronic origin should exist in the data. We show that such a source might exist in the AS-gamma data at 398-1000 TeV. Observations of this new type of sources could be used to constrain the Galactic magnetic field geometry. AI课代表总结：
本次讲座探讨了银河系内宇宙射线的传播及其与银河系磁场的关系，特别关注新的伽玛射线源——电视光环及弥漫伽马射线发射现象。
