Abstract

The first 2-year data on the diffuse gamma rays from the FERMI satellite are analyzed and compared with expectations from dark matter annihilation. Although the published results at intermediate latitudes do not confirm the EGRET GeV excess, the data towards the Galactic center are hard to explain with standard propagation models. Redoing a template shape fit to the data in about 900 independent sky directions reveals that the FERMI data are best described by including a DMA contribution from an NFW DM profile with a ringlike DM substructure, as required to describe the new precise data on the gas flaring and rotation curve.
