论文摘要
我们研究了标量tensor-gauss-bonnet理论的当前重力波数据的限制能力，该理论允许黑洞自发标量。在我们考虑的基准模型中，如果该理论引入的新长度比例$λ$相当，则必须标出一个缓慢旋转的黑洞，尽管该理论引入的$λ$，尽管任何质量的迅速旋转的黑洞在一般相对方面都与其对应物没有任何区别。考虑到这一点，我们使用重力波事件GW190814 $ \，\ unicode {x2014} \，其主要黑洞的旋转旋转的旋转且信号没有显示出标量化的主要$ \，\ unicode \ unicode {x2014} \，$，无法排除一个狭窄的区域narry Spame agarmeter narrage narrage narrage narrage narrage narrage narrage agarmeter。特别是，我们发现[56，96] 〜m_ \ odot} $的$ {λ\的值强烈不利于$ 0.1 $或更少的贝叶斯因子。我们还将第二个事件GW151226包括在我们的分析中，以说明当两个组件的旋转测量很差时可以提取哪些信息。
We examine the constraining power of current gravitational-wave data on scalar-tensor-Gauss-Bonnet theories that allow for the spontaneous scalarization of black holes. In the fiducial model that we consider, a slowly rotating black hole must scalarize if its size is comparable to the new length scale $λ$ that the theory introduces, although rapidly rotating black holes of any mass are effectively indistinguishable from their counterparts in general relativity. With this in mind, we use the gravitational-wave event GW190814$\,\unicode{x2014}\,$whose primary black hole has a spin that is bounded to be small, and whose signal shows no evidence of a scalarized primary$\,\unicode{x2014}\,$to rule out a narrow region of the parameter space. In particular, we find that values of ${λ\in [56, 96]~M_\odot}$ are strongly disfavored with a Bayes factor of $0.1$ or less. We also include a second event, GW151226, in our analysis to illustrate what information can be extracted when the spins of both components are poorly measured.
