论文摘要
我们探索了一种新的范式，以使用重力波观测来研究耗散暗物质模型。我们考虑了一个黑暗的原子模型，该模型可以预测二进制黑洞（例如GW190425）的形成，同时遵守大规模结构的约束，并改善缺失的卫星问题。使用从2015年9月12日至2019年10月1日的Ligo和处女座重力波数据，我们表明，将GW190425解释为暗物质黑孔二进制限制了Chandrasekhar的暗物质质量的暗物质为1.4 $ M_ \ m_ \ m_ \ odot $> 99.999.999.9 \％的proton n.95 g ever n.95 g ever n.95 g ever n.95 g ever in 0.95 g ever in 0.95 g ever in 0.95 g ever in 0.955深色分子的间距位于$ 10^{ - 3} $ eV附近，并在低温下限制了暗物质的冷却速率。
We explore a new paradigm to study dissipative dark matter models using gravitational-wave observations. We consider a dark atomic model which predicts the formation of binary black holes such as GW190425 while obeying constraints from large-scale structure, and improving on the missing satellite problem. Using LIGO and Virgo gravitational-wave data from 12th September 2015 to 1st October 2019, we show that interpreting GW190425 as a dark matter black-hole binary limits the Chandrasekhar mass for dark matter to be below 1.4 $M_\odot$ at $> 99.9\%$ confidence implying that the dark proton is heavier than 0.95 GeV, while also suggesting that the molecular energy-level spacing of dark molecules lies near $10^{-3}$ eV and constraining the cooling rate of dark matter at low temperatures.
