太阳邻域的小型及微型暗晕和中等质量黑洞

Dark mini-halos, micro-halos and intermediate-mass black holes in the solar neighborhood

银河系中可能存在103—104个中等质量的黑洞(102—103M⊙)和103个小型暗晕(质量为106M⊙)或1015个微型暗晕(质量10-6M⊙).离我们最近的微小暗晕和黑洞可能只有0.3—3000光年.如果暗物质是可以自湮灭的中超子(即最轻的中性超对称粒子,neutralino),这些子结构所产生的高能γ射线就有希望被下一代γ射线探测器(如GLAST)探测到.

Galaxies like the Milky Way may each be host to 103-104 intermediate mass black holes （ 10^2 M⊙-- 10^3 M⊙ ） and 10^3 minihalos of 10^6 M⊙ or 10^15 microhalos of 10^ -6 M⊙. Our nearest micro/mini - halos or black holes might be only 0.3--3000 light years away. If dark matter is composed of self - annihilating neutralinos, then these substructures hold the promise of being detectable by next generation γ- ray detectors such as GLAST.
