Description
Galactic diffuse gamma-ray emission (GDE) is produced by the galactic cosmic rays (CR) interacting with the interstellar medium (ISM) and radiation fields (ISRF). The GDE is a very important probe of CR propagation and interaction. Different from the measurements of CR particles in the local vicinity, the GDE enables a direct measurement of CR distribution in the Milky Way, and can thus provide much more important information of the production and propagation of CRs. LHAASO-WCDA, with a large area of 78000 m^2, can study VHE gamma-ray astronomy and GDE. In this talk, We will report the measurements of the diffuse emission from the Galactic plane in energy range from 1 TeV to 20 TeV with LHAASO-WCDA.
