Small‐scale dark matter clumps in the galactic halo

The small‐scale dark matter clumps can be disrupted in the Galaxy by tidal gravitational interactions. We performed the calculations of the tidal destruction of clumps by stars in the Galactic bulge and halo and by the Galactic disk itself. It is shown that the Galactic disc provides the dominant contribution to the tidal destruction of small‐scale clumps outside the bulge. The results obtained are crucial for calculations of the dark matter annihilation signal in the Galaxy.
