论文摘要
我们考虑了旋转CO(1-0),CO(2-1)和CO(3-2)过渡的线强度映射(LIM)的潜力,以检测从$ 0 <z <3 $的一般相对论的偏差,在非常通用的修改性重力模型的框架内,称为Horndeski理论。我们的预测假设多轨分析分别从物质功率谱和红移空间失真功率谱的前两个多物中获取信息。为了实现$ \ pm 0.1 $级别的限制,在动力学重力编织和普朗克质量演变参数上,MM-Wave Lim实验需要累积$ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\多数^的$ \ your \ 10^8-10^9^9 $ suppertormeter小时很大,大约为10^8-10^9 $小时,可用于2030年代可以部署的仪器。这样的测量将限制可用于标量调整的重力理论的其余参数空间的大部分。我们的建模代码公开可用。
We consider the potential for line intensity mapping (LIM) of the rotational CO(1-0), CO(2-1) and CO(3-2) transitions to detect deviations from General Relativity from $0 < z < 3$ within the framework of a very general class of modified gravity models, called Horndeski theories. Our forecast assumes a multi-tracer analysis separately obtaining information from the matter power spectrum and the first two multipoles of the redshift space distortion power spectrum. To achieve $\pm 0.1$ level constraints on the slope of the kinetic gravity braiding and Planck mass evolution parameters, a mm-wave LIM experiment would need to accumulate $\approx 10^8-10^9$ spectrometer hours, feasible with instruments that could be deployed in the 2030s. Such a measurement would constrain large portions of the remaining parameter space available to Scalar-Tensor modified gravity theories. Our modeling code is publicly available.
