Cosmic Gamma-Ray Background Anisotropies and Dark Matter Annihilation (15'+5')
 
The extragalactic cosmic gamma-ray background (CGB)  can provide signatures 
of Dark 
Matter Annihilation (DMA) not only through the imprint in the energy spectrum 
but also 
through the peculiar pattern and intensity of its anisotropies. These are 
expected to differ 
significantly with respect to a pure astrophysical origin of the CGB due to the 
peculiar 
quadratic dependence of the DMA signal from the DM density. 
I will discuss the DM signature expected in the power spectrum of the CGB 
anisotropies 
and the prospect for detection with the forthcoming GLAST observatory.  The 
talk is 
based on arXiv:0710.4136 (to appear inPRD).
