The Darkness of Spin-0 Dark Radiation
arXiv:1407.2501 · doi:10.1088/1475-7516/2015/01/017
Abstract
We show that the scattering of a general spin-0 sector of dark radiation off the pre-recombination thermal plasma results in undetectably small spectral distortions of the Cosmic Microwave Background.
