研究气态星团中黑洞自旋-质量关联及矢量共振弛豫，通过分析LIGO-Virgo-KAGRA合作团队报告的GW231123，发现其与预测的自旋-质量关联平台相符，且矢量共振弛豫平衡更优，为相关星团模型提供有力证据。
AI 中文摘要
在星团形成过程中，恒星黑洞通过吸积残余气体而生长，从而产生自旋-质量关联。此外，黑洞自旋往往与其在星团中的轨道角动量反平行。我们表明，LIGO-Virgo-KAGRA（LVK）合作团队报告的GW231123位于我们预测的自旋-质量关联的高质量、高自旋平台上，且贝叶斯证据比LVK先验概率更有利。此外，在再现相对自旋倾斜分布时，矢量共振弛豫（VRR）平衡比各向同性LVK先验更受青睐。联合贝叶斯因子表明支持的星团模型有有力证据。因此，GW231123与我们提出的产生相关黑洞质量和自旋并驱动自旋方向的通道一致。
英文摘要
During the formation of a star cluster a spin-mass correlation of stellar black holes is generated as they grow via accretion of the residual gas. Moreover, the black hole spin tends to be anti-aligned with its orbital angular momentum in the cluster. We show that GW231123, reported by the LIGO-Virgo-KAGRA (LVK) collaboration, lies on our predicted high-mass, high-spin plateau of the spin-mass correlation with positive Bayesian evidence over the LVK prior. Furthermore, vector resonant relaxation (VRR) equilibrium is favored over the isotropic LVK prior in reproducing the distribution of the relative spin tilt. The joint Bayes factor suggests strong evidence for the favored cluster models. GW231123 is thus consistent with our proposed channel that generates correlated black hole masses and spins, and drives the spins' orientations.
