Description
The Large High Altitude Air Shower Observatory (LHAAS) discovered a gamma-ray bubble spanning at least 100 deg^2 in ultra-high energy (UHE, >100TeV) band up to a few PeV in the direction of the star-forming region Cygnus X, implying the presence super PeVatron(s). I will introduce this study including LHAASO's observation and its implication for the origin of PeV cosmic rays.
