The UHE gamma-ray emission significance map and gamma-ray spectrum observed by LHAASO in W51 complex

Caption

(a)The UHE gamma-ray emission is clearly observed from the W51 complex, which hosts the supernova remnant W51C and star forming region W51B. (b) The “bending” feature around tens TeV indicates the cosmic-ray acceleration limit in the W51 complex at around 400TeV.
