论文摘要
我们考虑了几种众所周知的F（R）宇宙学模型并约束其参数，即偏差参数B和宇宙参数ω_m和H。我们首先在这些参数方面获得了Hubble速率H（Z）和光度距离D_L（Z）的分析近似值，然后根据宇宙中的圆柱形计算机和HII Galaxy Hubble图中的距离距离模量来测试这些参数，以使用模型不依赖性的Goussian Processes（gp）获得的观察性膨胀速率。我们首先仅基于宇宙天元素来优化模型，然后通过使用宇宙天文序和HII星系进行联合分析重复此过程。
We consider several well-known f(R) cosmological models and constrain their parameters, namely the deviation parameter b and the cosmological parameters Ω_m and h. We first obtain analytical approximations for the Hubble rate H(z) and the luminosity distance d_L(z) in terms of these parameters, and then test these against the observational expansion rate derived from cosmic chronometers and the distance modulus in the HII galaxy Hubble diagram, obtained in a model-independent way using Gaussian Processes (GP). We first optimize the models based solely on the cosmic chronometers and then repeat this process with a joint analysis using both the cosmic chronometers and HII galaxies.
