Abstract
The excess of electrons/positrons observed by the Pamela/ATIC/Fermi experiments gives rise to a noticeable amount of synchrotron and Inverse Compton Scattering (ICS) radiation when the exp+exp− interact with the Galactic Magnetic Field, and the InterStellar Radiation Field (ISRF). In particular, the ICS signal produced within the WIMP annihilation interpretation of the Pamela/ATIC excess shows already some tension with the EGRET data. On the other hand, 1 yr of Fermi data taking will be enough to rule out or confirm this scenario with a high confidence level. The ICS radiation produces a peculiar and clean “ICS Haze” feature, as well, which can be used to discriminate between the astrophysical and Dark Matter scenarios.
