Description

Non-gravitational interactions between dark and visible matter could transform the early history of our universe, heating or cooling the gas and contributing additional ionization and photons. I will describe the potential effects of energy injection from dark matter annihilation on the early universe, and the imprints it would leave in the cosmic microwave background and other observables. I will outline the resulting powerful constraints on light dark matter, and discuss some future directions.
