Bounds on Ultra-Light Hidden-Photon Dark Matter from 21cm at Cosmic Dawn

Abstract

Ultra-light hidden-photon dark matter produces an oscillating electric field in the early Universe plasma, which in turn induces an electric current in its ionized component whose dissipation results in heat transfer from the dark matter to the plasma. This will affect the global 21cm signal from the Dark Ages and Cosmic Dawn. In this work we focus on the latter, in light of the reported detection by the EDGES collaboration of an absorption signal at frequencies corresponding to redshift z~17. By measuring the 21cm global signal, a limit can be placed on the amount of gas heating, and thus the kinetic mixing strength $\epsilon$ between the hidden and ordinary photons can be constrained. Our inferred 21cm bounds on $\epsilon$ in the mass range $10^{-23}\mathrm{eV}\lesssim m_{\chi }\lesssim 10^{-13}\mathrm{eV}$ are the strongest to date.
