Dark matter in the Milky Way: a precision era


The existence of a "dark" component of matter, namely of a class of particles not interacting with electromagnetic radiation, not belonging to the Standard Model, yet coupled with gravity, is a central tenet of modern Cosmology. Its presence in different environments on a large range of scales has been proven with astrophysical observations of diverse nature as well as its non-belonging to the Standard Model. Yet, its nature eludes us as of today. The synergy between collider probes, astrophysical signatures and Earth based experiments is at the basis of the current effort to frame the nature of the Dark Matter particles. This project aims at using local astrophysical observables, namely dynamical and morphological information on our own Galaxy, in order to improve our knowledge and reduce the uncertainties in this multi-channel search. The goal of this project is two-fold: a)obtaining unprecedented, model-independent information on the spatial and dynamical distribution of the Dark Matter in the Milky Way, by making use of the most up-to-date observations; b)use such information in order to thin out the uncertainties on current and future indirect and direct detection experiments. Beside its crucial use in the framework of particle physics, the information provided will represent an observational determination of the dark matter structure in our own Galaxy, and be of relevance for the understanding of Galaxy formation in a cosmological context.
