TL;DR: Observations of an extended region of very-high-energy gamma-ray emission correlated spatially with a complex of giant molecular clouds in the central 200 parsecs of the Milky Way indicate that the cosmic rays giving rise to the gamma-rays are likely to be protons and nuclei rather than electrons.
