The Chang-Yun Fan cosmic ray series 第8期
Cosmic ray studies started more than a hundred years ago, with countless articles and numerous textbooks published. Advanced numerical codes have been developed to describe cosmic ray propagation and acceleration, and, at first glance, the field reached not only its maturity, but even its old age. Thus, it is shocking to find out the fundamental processes that were missed by the generations of earlier researchers or were incorrectly described.To support my point, I will discuss a few topics that I have worked on. Those include perpendicular super diffusion, mirror diffusion,acceleration, and the Levi flights of cosmic rays.

格物致理第99期：GRB afterglows: particle acceleration, emission, and hydrodynamic evolution
Gamma-Ray Bursts are produced by stellar explosions that channel part of their energy into ultrarelativistic jets. Plunging into curcumburst medium,these jets form relativistic shocks, whose prolonged emission is known as GRB afterglow. This emission is a combination of synchrotron and inverse Compton radiation from accelerated electrons.

格物致理第97期：超高能弥散伽马射线观测和模型研究
弥散伽马射线一般认为产生于宇宙线和星际介质的相互作用，因此是研究宇宙线分布和传播模型的重要探针。TeV以上能段的弥散伽马射线需要地面实验测量，受限于灵敏度而长期以来精度不高。我国建造的高海拔宇宙线观测站LHAASO以其超宽能段覆盖和超高观测灵敏度，显著地改善了这一局面。本报告将介绍拉索对TeV-PeV能段银盘弥散伽马辐射的精确测量以及对观测结果的可能物理解释。
