Description
The Cosmic Microwave Background (CMB) spectrum matches that of a perfect blackbody with very high precision. Therefore, any model that distorts this spectrum is highly constrained. Motivated by certain dark sector models, we consider distortions caused by an axion-dark photon-photon coupling. In an axion dark matter background, this coupling converts CMB photons into invisible dark photons. We present the details of this distortion and the constraints on the axion-dark photon-photon coupling that result from it.
