Abstract
The smaller Dark Matter structures predicted in the CDM scenario have a mass in the range [10e-12;10e-4] Msun, depending on the underlying particle physics. It is however not clear what is the inner DM structure of such halos, nor which is the real survival probability during mergers. We show how these open questions result in a large uncertainty in the prediction of the observability of such halos with indirect detection tecniques. We show predictions for the observability of the dwarf galaxies using dark matter density profiles derived from the available data on velocity dispersion curves.
