Abstract:

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 the current understanding of the CRs in our Galaxy, mostly from an observational point of view, especially from the related gamma-ray astronomy, and discuss the possible interplay between CRs and star formation processes. I will also discuss the prospect in pinning down the origin of CRs with LHAASO and the planned Chinese Cerenkov telescope array.


Bio:

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.
