Limits on the Light Dark Matter-Proton Cross Section from Cosmic Large-Scale Structure

We set the strongest limits to date on the velocity-independent dark matter (DM)-proton cross section σ for DM masses m=10  keV to 100 GeV, using large-scale structure traced by the Lyman-alpha forest: e.g., a 95% lower limit σ
