# Cosmological constraints on the gravitational interactions of matter and dark matter

@article{Bai2015CosmologicalCO, title={Cosmological constraints on the gravitational interactions of matter and dark matter}, author={Yang Bai and Jordi Salvado and Ben A. Stefanek}, journal={Journal of Cosmology and Astroparticle Physics}, year={2015}, volume={2015}, pages={029 - 029} }

Although there is overwhelming evidence of dark matter from its gravitational interaction, we still do not know its precise gravitational interaction strength or whether it obeys the equivalence principle. Using the latest available cosmological data and working within the framework of ΛCDM, we first update the measurement of the multiplicative factor of cosmology-relevant Newton's constant over the standard laboratory-based value and find that it is consistent with one. In general relativity…
