Cosmic microwave background constraints on coupled dark matter
We study CMB constraints on a scenario where a fraction of dark matter is non-minimally coupled to a massless scalar field and dark energy is in the form of a cosmological constant. In this case, there is an extra gravity-like fifth force which can affect the evolution of the Universe enough to have...
