Implications of the possible 21-cm line excess at cosmic dawn on dynamics of interacting dark energy
In this Letter we study implications of the possible excess of 21-cm line global signal at the epoch of cosmic dawn on the evolutions of a class of dynamically interacting dark energy (IDE) models. We firstly summarize two dynamical mechanisms in which different background evolutions can exert consi...
