"Multifrequency Brightness of Galactic Dark Matter"


The rare annihilations of WIMPS accumulated in the Galaxy are responsible for emission in several frequency bands, each one able to provide us with precious information about the properties of the WIMP particle candidate. I will discuss mainly two cases: 1) diffuse gamma ray emission from a clumpy halo; 2) Electron-positron production and their synchrotron radiation in clumpy structures. The latter point represents a completely new way of looking for WIMP annihilation in the Galaxy, by searching for perturbations of the very well known anisotropies of the cosmic microwave background.
