We explore the possible spectrum of binary mergers of subsolar mass black holes formed out of dark matter particles interacting via a dark electromagnetism. We estimate the properties of these dark black holes by assuming that their formation process is parallel to Population-III star formation, except that dark molecular cooling can yield a smaller opacity limit. We estimate the binary coalescence rates for the Advanced LIGO and Einstein telescope, and find that scenarios compatible with all current constraints could produce dark black holes at rates high enough for detection by Advanced LIGO.
我们探索了暗物质粒子通过暗电磁相互作用形成的亚太阳质量黑洞的双星合并的可能范围。我们通过假设它们的形成过程与 III 族星形成平行，只是暗分子冷却可以产生更小的不透明度极限，来估计这些暗黑洞的性质。我们估计了高级 LIGO 和爱因斯坦望远镜的双星并合率，发现与所有当前约束条件兼容的情景可以以足够高的速率产生暗黑洞，以便被高级 LIGO 检测到。
