成团的原始黑洞作为暗物质的强约束

Strong constraints on clustered primordial black holes as dark matter

Torsten Bringmann, Paul Frederik Depta, Valerie Domcke, Kai Schmidt-Hoberg

摘要:

暗物质以原始黑洞形式存在的想法最近又死灰复燃,这是由LIGO探测到的来自双黑洞合并的引力波引发的。在这种情况下,有人认为,一个大的原始黑洞的初始集群可以帮助减轻这种情况下的强大约束。在这项工作中,我们表明,相反,与大的初始集群的问题是加剧和约束的原始黑洞暗物质变得压倒性的强大。

英文摘要:

The idea of dark matter in the form of primordial black holes has seen a recent revival triggered by the LIGO detection of gravitational waves from binary black hole mergers. In this context, it has been argued that a large initial clustering of primordial black holes can help alleviate the strong constraints on this scenario. In this work, we show that on the contrary, with large initial clustering the problem is exacerbated and constraints on primordial black hole dark matter become overwhelmingly strong.
