Interacting dark energy: possible explanation for 21-cm absorption at cosmic dawn
Abstract A recent observation points to an excess in the expected 21-cm brightness temperature from cosmic dawn. In this paper, we present an alternative explanation of this phenomenon, an interaction in the dark sector. Interacting dark energy models have been extensively studied recently and there...
