Description
We consider a model for dark matter with a dark U(1) charge and where the gauge mediator is described by a non-linear electromagnetic theory, being the Born-Infeld theory a paradigmatic example. These theories are equipped with a K-mouflage screening mechanism so that only at late times and on small scales will the dark electromagnetic force have a non-negligible effect. This scenario naturally leads to a cosmological evolution where the late-time universe is described by a Lemaître inhomogeneous model. The potential role of this model regarding the H0 tension will be discussed.
