Abstract

We consider Thomson-like processes between dark matter dark photons and free electrons in the Milky Way. The result is a radio signal background that can be detectable with current or future radio telescope arrays. In particular, we computed sensitivity prospects for the Atacama Large Millimeter Array radio telescope and for the future Square Kilometer Array, concluding that unconstrained parameter space in a wide range of dark photon masses can be probed.
