重建暗物质与全息暗能量之间的相互作用

Reconstructing the interaction between the dark matter and holographic dark energy

Shao-Feng Wu, Peng-Ming Zhang, Guo-Hong Yang

摘要:

以参数化状态方程和未来事件视界为红外截止长度,重建了暗物质与全息暗能量的相互作用速率。结果表明,192 SNIa和BAO观测的观测约束允许负相互作用在大范围内存在。此外,通常的唯象描述在很多情况下不能很好地描述重构的相互作用。还讨论了其他可能的相互作用。

英文摘要:

We reconstruct the interaction rate between the dark matter and the holographic dark energy with the parameterized equation of states and the future event horizon as the infrared cut-off length. It is shown that the observational constraints from the 192 SNIa and BAO measurement permit the negative interaction in the wide region. Moreover, the usual phenomenological descriptions can not describe the reconstructed interaction well for many cases. The other possible interaction is also discussed.
