Bo-Yu Pu, Xiao-Dong Xu, Bin Wang, Elcio Abdalla

摘要:

本文研究了一类早期暗能量模型,它在宇宙的早期具有大量的暗能量。在线性近似下,我们研究了早期暗能量涨落对结构生长和CMB功率谱的影响。进一步研究了早期暗能量与暗物质的相互作用对结构生长和CMB的影响。最后,通过对不同观测结果的分析,我们对早期的暗能量模型参数和暗扇区之间的耦合进行了约束。

英文摘要:

We study a class of early dark energy models which has substantial amount of dark energy in the early epoch of the universe. We examine the impact of the early dark energy fluctuations on the growth of structure and the CMB power spectrum in the linear approximation. Furthermore we investigate the influence of the interaction between the early dark energy and the dark matter and its effect on the structure growth and CMB. We finally constrain the early dark energy model parameters and the coupling between dark sectors by confronting to different observations.
