Abstract
The existence of dark matter at scales of a few parsecs down to 10^-5 pc at the center of the Galaxy has been considered in the literature. Under the assumption that a dark matter clump exists, the study of the gamma-ray emission from the galactic center allows us to constraint both the mass and the size of this distribution. Here we also discuss the constraints coming from the analysis of the S2 and S16 stars orbiting around SgrA*.File in questo prodotto:
