Exotic energy injection in the early universe II: CMB spectral distortions and constraints on light dark matter

Hongwan Liu, Wenzer Qin, Gregory W. Ridgway +1

We calculate the post-recombination contribution to the Cosmic Microwave Background (CMB) spectral distortion due to general exotic energy injections, including dark matter (DM) de…

Exotic energy injection in the early universe I: a novel treatment for low-energy electrons and photons

Hongwan Liu, Wenzer Qin, Gregory W. Ridgway +1

Decaying or annihilating dark matter and other exotic energy injections can modify the spectrum of the universe's photon bath, resulting in e.g. new contributions to spectral disto…
