我们认为大质量的原始黑洞是暗物质的主要形式。黑洞的形成给物质密度波动增加了泊松噪声。我们使用Lyα森林观测来约束这个泊松项，它约束黑洞质量小于大约104 M☉的几倍。我们还发现，黑洞少于103个的结构现在已经蒸发了。
We consider the possibility that massive primordial black holes are the dominant form of dark matter. Black hole formation adds a Poisson noise to the matter density fluctuations. We use Lyα forest observations to constrain this Poisson term, which constrains the black hole masses to be less than approximately a few times 104 M☉. We also find that structures with less than ~103 black holes evaporate by now.
