英文摘要In this paper, we report the detection of the very-high-energy (VHE, 100 GeV < E < 100 TeV) and ultra-high-energy (UHE, E > 100 TeV) gamma-ray emissions from the direction of the young star-forming region W43, observed by the Large High Altitude Air Shower Observation (LHAASO). The extended gamma-ray source was detected with a significance of similar to 16 sigma by KM2A and similar to 17 sigma by WCDA, respectively. The angular extension of this gamma-ray source is about 0.5 degrees, corresponding to a physical size of about 50 pc. We discuss the origin of the gamma-ray emission and possible cosmic ray acceleration in the W43 region using multi-wavelength data. Our findings suggest that W43 is likely another young star cluster capable of accelerating cosmic rays (CRs) to at least several hundred TeV.
