Abstract

Hubble tension is a key problem in cosmology, which may signal a new physics. We perform a kinematics-dynamics double test of Hubble tension through the Gaussian processes. Reconstructions under the two types of

H_{0}

priors from the current supernovae, transversal baryon acoustic oscillation, Cosmic Chronometers and strong gravitational lensing data indicate that the kinematics jerk and dynamics equation of state of dark energy are consistent with the fiducial

Λ

CDM model within 68% confidence level, except at some redshift interval. Importantly, we find that the latter three observational data are sensitive to the Hubble constant, which have a potential to test the Hubble tension. Unfortunately, uncertainties of the current observational data are too large to distinguish the Hubble tension. We make a forecast using the simulated supernovae and strong gravitational lensing data. The supernovae from WFIRST can present a much tighter constraint on the reconstructions. It has a large potential to test the Hubble tension.

通过高斯过程对哈勃张力的运动学-动力学双重检验

哈勃张力是宇宙学中的一个关键问题，它可能预示着一种新的物理学。我们通过高斯过程对哈勃张力进行了运动学-动力学双重测试。在当前超新星、横重子声学振荡、宇宙天文钟和强引力透镜数据的两种H0先验条件下重建表明，暗能量的运动学抖动和动力学状态方程在68%的置信水平内与基准ΛCDM模型一致，除了在一些红移区间。重要的是，我们发现后三个观测数据对哈勃常数很敏感，这有可能测试哈勃张力。不幸的是，目前观测数据的不确定性太大，无法区分哈勃张力。我们利用模拟的超新星和强引力透镜数据进行了预测。来自WFIRST的超新星可以对重建提供更严格的约束。它有很大的潜力来测试哈勃的张力。

期刊介绍： Annals of Physics presents original work in all areas of basic theoretic physics research. Ideas are developed and fully explored, and thorough treatment is given to first principles and ultimate applications. Annals of Physics emphasizes clarity and intelligibility in the articles it publishes, thus making them as accessible as possible. Readers familiar with recent developments in the field are provided with sufficient detail and background to follow the arguments and understand their significance. The Editors of the journal cover all fields of theoretical physics. Articles published in the journal are typically longer than 20 pages.
