论文摘要
渐近安全的量子重力是一种有前途的候选场景，可为爱因斯坦重力的有效量子场理论提供紫外线延伸。该理论的基础是量子场理论非常成功的框架，该理论已经对电磁和核相互作用进行了广泛的测试。但是，渐近安全量子重力的观察性测试更具挑战性。最近，已经提出了受渐近安全量子重力启发的旋转黑洞度量，这打开了该理论的天体物理测试的可能性。在本文中，我们显示了X射线反射光谱的功能，从分析X射线二进制二进制GRS 1915+105的Suzaku观察中，限制了无量纲的固定点值$γ$。我们将这些约束与从黑洞成像获得的约束进行了比较。
Asymptotically safe quantum gravity is a promising candidate scenario to provide a UV extension for the effective quantum field theory of Einstein's gravity. The theory has its foundations on the very successful framework of quantum field theory, which has been extensively tested for electromagnetic and nuclear interactions. However, observational tests of asymptotically safe quantum gravity are more challenging. Recently, a rotating black hole metric inspired by asymptotically safe quantum gravity has been proposed, and this opens the possibility of astrophysical tests of the theory. In the present paper, we show the capabilities of X-ray reflection spectroscopy to constrain the inverse dimensionless fixed-point value $γ$ from the analysis of a Suzaku observation of the X-ray binary GRS 1915+105. We compare these constraints with those obtained from black hole imaging.
