Description
The Tibet Air Shower Array is located in Yangbajing, China, and has been operated since 1990. Its air shower array covers a geometrical area of 65,700 m$^2$ by featuring about 600 plastic scintillation detectors and captures air showers produced by cosmic rays with energies from 10$^{12}$ eV to more than 10$^{15}$ eV. In particular, since the installation of an underground muon detector array in 2014, the experiment has been performing observations sensitive to the celestial gamma rays with energies reaching beyond 10$^{14}$ eV, the sub-PeV energy range. The use of the underground muon detector combined with the surface air shower array resulted in the first detections of sub-PeV gamma rays from the Crab Nebula and sub-PeV Galactic diffuse gamma rays, and identifications of some PeVatron candidates, such as SNR G106.3+2.7. This talk will mainly focus on how the Tibet AS$\gamma$ experiment has been contributing to the development of sub-PeV gamma-ray astronomy and present some interpretations of the results accounting for those given by other gamma-ray observatories.
