论文摘要
质量范围$（30 $ - $ 100）〜m _ {\ odot} $的原始黑洞（PBH）是暗物质的有趣候选者，因为它们位于微透镜和宇宙微波背景约束之间的狭窄窗口中。但是，从Ligo和处女座实验观察到的二进制合并率受到严格的限制。在得出这些约束时，PBH被视为Schwarzschild质量，而在我们这里提出的不断扩展的宇宙中，更仔细的分析导致时间依赖时间。这意味着要形成黑洞二进制的一组严格的条件，这意味着黑洞合并的速度要比以前计算得更快，即在Ligo/Wirgo观察到的合并之前。观察到的二进制文件是在银河系中融合的二进制文件，并与数据一致。这重新打开了以Ligo-Mas PBH形式进行暗物质的可能性。
Primordial black holes (PBHs) in the mass range $(30$--$100)~M_{\odot}$ are interesting candidates for dark matter, as they sit in a narrow window between microlensing and cosmic microwave background constraints. There are however tight constraints from the binary merger rate observed by the LIGO and Virgo experiments. In deriving these constraints, PBHs were treated as point Schwarzschild masses, while the more careful analysis in an expanding universe we present here, leads to a time-dependent mass. This implies a stricter set of conditions for a black hole binary to form and means that black holes coalesce much more quickly than was previously calculated, namely well before the LIGO/Virgo's observed mergers. The observed binaries are those coalescing within galactic halos, with a merger rate consistent with data. This reopens the possibility for dark matter in the form of LIGO-mass PBHs.
