A one-zone model fitted to radio observations of WR 102's bubble predicts that protons accelerated at the wind shock dominate high-energy emission but produce an undetectable gamma-ray flux.
Numerical transport modeling of the Cygnus Bubble finds that spatially dependent Bohm diffusion and strong suppression of the diffusion coefficient over at least 150 pc are required to match the observed gamma-ray spectrum and morphology, implying extreme assumptions for steady hadronic acceleration
Diffuse gamma-ray emission detected toward Berkeley 87 with 0.36° extension and photon index 2.68, favoring a hadronic origin due to dense gas and stellar winds.
