摘要:

可行的f(R)模型的约束条件进行了调查,面对的多极功率谱的发光的红色星系样本的斯隆数字巡天数据发布7的理论预测。我们得到了宇宙学大尺度结构尺度上f(R)模型的康普顿波长参数的一个约束。本文还探讨了用未来的红移测量来约束康普顿波长参数的前景。证明了红移空间扭曲对于在宇宙学尺度上检验引力理论的有用性。

英文摘要:

A constraint on the viable f(R) model is investigated by confronting theoretical predictions with the multipole power spectrum of the luminous red galaxy sample of the Sloan Digital Sky survey data release 7. We obtain a constraint on the Compton wavelength parameter of the f(R) model on the scales of cosmological large-scale structure. A prospect of constraining the Compton wavelength parameter with a future redshift survey is also investigated. The usefulness of the redshift-space distortion for testing the gravity theory on cosmological scales is demonstrated.
