Early-Universe constraints on dark matter-baryon scattering and their implications for a global 21 cm signal
We present and compare several cosmological constraints on the cross section for elastic scattering between dark matter (DM) and baryons, for cross sections with a range of power-law dependences on the DM-baryon relative velocity v, especially focusing on the case of σ∝v^{-4}. We study constraints s...
