题目：Investigating Cosmic rays with PeV and MeV astronomy

　　报告人：杨睿智

　　报告人简介：Prof. Ruizhi Yang got the Bachelor degree in theoretical physics in university of Science and Technology of China (USTC) in 2007. He obtained his PhD in Purple mountain observatory in 2013. After 6 years postdoc career in Max-plank-institute for nuclear physics in Heidelberg, Germany, he joined the department of astronomy in USTC. His research interests are gamma-ray astronomy, cosmic ray science.

　　摘要： Cosmic rays (CRs) is one of the most important component in the interstellar medium (ISM) in our Galaxy. The high energy CRs will interact with the ambient gas and produce gamma-rays, which dominate the diffuse gamma-ray background, while the low energy CRs may play a leading role in the ionization in dense cores of molecular clouds and govern the star formation process. I will talk about some recent progresses in investigating CR with both PeV and MeV gamma-ray astronomy. I will also discuss the prospect in pinning down the origin of CRs with the planned Chinese Cerenkov telescope array and possible future MeV instruments.
