来自修正重力的PLANCK实验的更新约束

Updated constraints from the PLANCK experiment on modified gravity

Andrea Marchini, Valentina Salvatelli

摘要:

对广义相对论作用的修正产生了一种不同的模式,使宇宙结构在一定长度尺度以下的生长在宇宙微波背景(CMB)各向异性上留下印记。本文利用普朗克卫星实验的最新数据重新检验了f(R)模型的长度尺度参数B0的上限。我们还研究了组合约束时,包括哈勃空间望远镜H0测量和重子声学振荡测量的SDSS,WiggleZ和BOSS调查。

英文摘要:

A modification of the action of the general relativity produces a different pattern for the growth of the cosmic structures below a certain length-scale leaving an imprint on the cosmic microwave background (CMB) anisotropies. We re-examine the upper limits on the length-scale parameter B0 of f (R) models using the recent data from the Planck satellite experiment. We also investigate the combined constraints obtained when including the Hubble Space Telescope H0 measurement and the baryon acoustic oscillations measurements from the SDSS, WiggleZ and BOSS surveys.
