Description

The new FERMI data on the diffuse Galactic gamma rays shows a large unidentifiedcomponent. The compatibility with a dark matter annihilation (DMA) contribution has been investigated. Furthermore, the data is compared with extremely precise new data on the outer rotation curve from maser interferometry and gasflaring. Both measurements indicate a ring of dark matter in the outer Galaxy in agreement with the hypothesis of the tidal disruption of the Canis Major dwarf Galaxy. Also the FERMI data is consistent with this hypothesis. The antiproton data from PAMELA is compared with different propagation models. It is shown that as much as half of the antiprotons may originate from DMA.
