Dark Matter visible by the EGRET Excess of Diffuse Galactic Gamma Rays?
  The public data from the EGRET space telescope on diffuse galactic gamma rays in the energy range from 0.1 to 10 GeV show an excess for energies above 1 GeV in comparison with the expectations from conventional galactic models. This excess shows all the key features of Dark Matter Annihilation (DMA), like being observable in al sky directions with a shape corresponding to a WIMP mass between 50 and 100 GeV. The intensity of the excess in various directions can be used to reconstruct the DM profile, which - combined with the distribution of visible matter - allows to calculate the rotation curve of our Galaxy. Its peculiar shape, which is not flat, but shows a minimum and maximum, is indeed reconstructed from the gamma rays, thus proving that the EGRET excess traces the DM. Furthermore, the spectral shape of the excess is consistent with mSUGRA and the WMAP relic density for rather heavy squarks and sleptons - O(1 TeV) - and light charginos, neutralinos and gluinos (below 500 GeV).
