将暗能量与下一代大尺度观测相结合的测试

Testing coupled dark energy with next-generation large-scale observations

Luca Amendola, Valeria Pettorino, Claudia Quercellini, Adrian Vollmer

摘要:

将暗能量耦合到暗物质提供了一种最简单的方法来有效地在大尺度上修改重力,而不受局部(即太阳系)观测的强烈约束。耦合暗能量的模型在过去已经被研究过几次,并且已经受到宇宙微波背景实验的显著限制。在本文中,我们估计的约束条件,未来的大规模观测将能够把耦合和一般的所有参数的模型。我们结合了宇宙微波背景、层析弱透镜、红移畸变和功率谱探测。我们表明,下一代的观测可以提高目前的约束耦合到暗物质的两个数量级,这种约束是互补的耦合到重子目前的太阳系的界限。

英文摘要:

Coupling dark energy to dark matter provides one of the simplest way to effectively modify gravity at large scales without strong constraints from local (i.e. solar system) observations. Models of coupled dark energy have been studied several times in the past and are already significantly constrained by cosmic microwave background experiments. In this paper we estimate the constraints that future large-scale observations will be able to put on the coupling and in general on all the parameters of the model. We combine cosmic microwave background, tomographic weak lensing, redshift distortions and power spectrum probes. We show that next-generation observations can improve the current constraint on the coupling to dark matter by two orders of magnitude; this constraint is complementary to the current solar-system bounds on a coupling to baryons.
