Description
We have implemented the Richardson–Lucy deconvolution algorithm for KM2A. Using this algorithm，our analysis reveals that the morphology of the TeV emission from the Cygnus X region closely resembles that observed in both infrared and radio bands. By comparing the TeV morphology with infrared emission features, we find morphological evidence linking the TeV radiation to either the Strömgren sphere ionized by the Cygnus OB2 association or—more plausibly—to the supershell/superbubble structure centered on Cygnus OB2. This strongly supports a hadronic origin for the diffuse TeV emission in the Cygnus X region, and further indicates a spatial association with the Cygnus OB2–driven superbubble.
