论文摘要
观察到的黑洞自旋分布可以约束轴突状颗粒的质量。在这项工作中，我们使用最近改进的超级公式更新了先前的计算，这更准确。通过贝叶斯分析，还仔细研究了合并时间尺度的效果。合并时间$τ_\ mathrm {m} $集成后，我们找到了两个偏爱的质量范围$ 7.94 \ times10^{ - 13}〜\ text {ev} \ leqleqμ\ leq 8.71 $ 1.44 \ times10^{ - 12}〜\ text {ev} \leqμ\ leq1.74 \ times10^{ - 12}〜\ text {ev} $。这两个偏爱的范围不取决于$τ_\ Mathrm {M} $的先前分布。我们还找到了范围$ -12.80 \ leq \ log_ {10}（μ/\ text {ev}）\ leq-122.34 $的证据的强度，该分析被固定的$τ_\ text {m} $在分析中被排除在分析中，可以用$τ_\ nathrm} $} $ {m} $} $} $} $} $} $} $} $ i}增加。
The mass of the axion-like particles could be constrained by the observed black hole spin distribution. In this work, we update the previous calculations using the recently improved superradiance formula, which is much more accurate. The effect of the merger time scale is also carefully investigated with Bayesian analysis. After integration of the merger time $τ_\mathrm{M}$, we find two favoured mass ranges $7.94\times10^{-13}~\text{eV}\leqμ\leq8.71\times10^{-13}~\text{eV}$ and $1.44\times10^{-12}~\text{eV}\leqμ\leq1.74\times10^{-12}~\text{eV}$ . These two favored ranges do not depend on the prior distribution of the $τ_\mathrm{M}$. We also find the strength of evidence for the range $-12.80\leq\log_{10}(μ/\text{eV})\leq-12.34$, which is excluded in the analysis with fixed $τ_\text{M}$, could increase by several orders of magnitude with $τ_\mathrm{M}$ averaged.
