Very-high-energy gamma-ray observations of the central part of the Milky Way Galaxy allow for morphological study of cosmic-ray propagation around the supermassive black hole Sgr A*. An interpretation of the diffuse gamma-ray component. which spans a few hundred parsecs in longitude. is the PeVatron scenario: the spectral energy distribution follows a power law up to a few tens of TeV. https://parisnaturalfoodes.shop/product-category/hawthorn-ii/
