In this letter we construct the Hubble diagram for a universe where dark matter is universally charged under a dark non-linear electromagnetic force which features a screening mechanism of the K-mouflage type for repulsive forces. By resorting to the Newtonian approximation, we explicitly show that the cosmological evolution generates an inhomogeneous Hubble diagram that corresponds to a curvature dominated expansion at short distances and converges to the cosmological one of ΛCDM. We discuss the potential impact of this inhomogeneous profile on the Hubble tension. For completeness, we explicitly show how the Newtonian approximation can be derived from an inhomogeneous relativistic Lematre model.

来自矢量 K-mouflage 的非齐次哈勃图
在这封信中,我们为一个宇宙构建了哈勃图,其中暗物质在暗非线性电磁力下普遍带电,其特征是 K-mouflage 类型的排斥力屏蔽机制。通过采用牛顿近似,我们明确地表明宇宙演化产生了一个不均匀的哈勃图,该图对应于短距离的曲率主导膨胀,并收敛到 ΛCDM 的宇宙学之一。我们讨论了这种非均匀分布对哈勃张力的潜在影响。为了完整起见,我们明确展示了如何从非齐次相对论 Lematre 模型导出牛顿近似。
