Description
The field of Dark Matter Indirect Detection is in a thriving but somewhat chaotic moment: quite a few hints of possible detection of signals of DM (over a large range of masses and, in general, inferred properties) are confronted with stringent constraints, often based on the same experiments that provide the possible hints. In turn, this spurs a lot of theoretical activity, aimed at phenomenologically analyzing the claims and, perhaps, at embedding them in wider model building. I will briefly review the current status of the searches and then discuss one of the currently most debated hints (the possible excess in gamma rays at GeV energies from the Galactic Center detected in data from the Fermi satellite), as a paradigmatic example of the current situation.
