Abstract
We argue that the Milky Way (MW) contains intermediate mass black holes (IMBHs) of mass . Some IMBHs are naked, and some are enshrouded by dense dark minispikes and by minihalos of . The IMBH is formed off-center by gas accretion in a minihalo. These dense minihalos (the nearest at about 2 kpc) survive mostly without tidal stripping by the MW, and are largely invisible except that their pointlike neutralino annihilation signals (with bolometric luminosities of within of their centers) stand out well above the MW background and are more luminous than outer dwarf satellite galaxies.
