摘要:

研究了弱引力波在暗能量背景下的传播。的考虑是在一个近似的方法的框架内进行的宇宙尺度因子扩展为一个幂级数的相对较小的值的红移对应的时代,目前的宇宙加速膨胀。对于几种不同的暗能量模型,我们得到了引力波的色散关系,通过与观测数据的比较,可以用来估计每个特定模型的可行性。

英文摘要:

The propagation of weak gravitational waves on the background of dark energy is studied. The consideration is carried out within the framework of an approximate approach where the cosmological scale factor is expanded as a power series for relatively small values of the redshift corresponding to the epoch of the present accelerated expansion of the Universe. For several different dark energy models, we obtain dispersion relations for gravitational waves which can be used to estimate the viability of every specific model by comparing with observational data.
