We find no unambiguous evidence for a significant excess with respect to expectations. Yet, some preference for a flatter energy dependence of the diffusion coefficient starts to emerge. Also, we provide a first assessment of the room left for exotic components such as Galactic Dark Matter annihilation or decay, deriving new stringent constraints.","authors_text":"Ga\\\"elle Giesen, Marco Cirelli, Mathieu Boudaud, Pasquale D.
