论文摘要
本文探讨了黑暗的非线性电磁扇形在宇宙中具有净深度净电荷的后果。宇宙学动力学可以通过Lema-tre模型来描述，并得益于由电磁非线性驱动的筛选机制来理解，这些筛选机制抑制了小尺度上的黑力。只有在低红移时，当筛选量表进入哈勃地平线时，才能开始感觉到黑暗的排斥。这种排斥力增强了哈勃常数的局部价值，因此为解决哈勃张力提供了有希望的场景。值得注意的是，深色电磁相互作用可能对特殊速度产生至关重要的影响，即引入其重建方法偏见，并有可能解释存在黑暗流的存在。
This Essay explores consequences of a dark non-linear electromagnetic sector in a Universe with a net dark charge for matter. The cosmological dynamics can be described by a Lemaître model and understood thanks to a screening mechanism driven by the electromagnetic non-linearities that suppress the dark force on small scales. Only at low redshift, when the screening scale enters the Hubble horizon, do cosmological structures commence to feel the dark repulsion. This repulsive force enhances the local value of the Hubble constant, thus providing a promising scenario for solving the Hubble tension. Remarkably, the dark electromagnetic interaction can have a crucial impact on peculiar velocities, i.e. introducing a bias in their reconstruction methods, and having the potential to explain the presence of a dark flow.
