Dark matter spikes and annihilation radiation from the galactic center
(American Physical Society, 2002-05-13)
The annihilation rate of weakly interacting cold dark matter particles at the galactic center could be greatly enhanced by the growth of a density spike around the central supermassive black hole (SBH). Here we discuss the ...
