Fig. 3

Distribution of DM density ρDM in our Galaxy as a function of distance from the Galactic Centre according to the Navarro–Frenk–White profile62 (top). Graphical illustration of \({}^{3}\overline{{{{\rm{He}}}}}\) production from cosmic-ray interactions with interstellar gas or DM (χ) annihilations (bottom). The yellow halo represents the heliosphere and the Earth, Sun and positions of the Voyager 1, AMS-02 and GAPS experiments are depicted, too.
