论文摘要
我们表明，由于二进制黑洞合并速率对宇宙结构形成的依赖性，引力波有可能揭示暗物质的微物理特性，这本身高度依赖于暗物质的情况。特别是，我们证明了对小规模结构的抑制（例如由相互作用，温暖或模糊的暗物质引起的）导致Redshifts $ z \ gtrsim5 $的二进制黑洞合并速率的显着降低。这表明未来的重力波观测将为$λ$ CDM模型提供新的物理探测。
We show that gravitational waves have the potential to unravel the microphysical properties of dark matter due to the dependence of the binary black hole merger rate on cosmic structure formation, which is itself highly dependent on the dark matter scenario. In particular, we demonstrate that suppression of small-scale structure -- such as that caused by interacting, warm, or fuzzy dark matter -- leads to a significant reduction in the rate of binary black hole mergers at redshifts $z\gtrsim5$. This shows that future gravitational-wave observations will provide a new probe of physics beyond the $Λ$CDM model.
