How to use molecular clouds to study the propagation of cosmic rays in the Galaxy
cosmic rays:origin and propagation gamma rays molecular clouds
2010/11/12
Observations of molecular clouds in the gamma ray domain provide us with a tool to study the distribution of cosmic rays in the Galaxy. This is because cosmic rays can penetrate molecular clouds, unde...
