Analytic Fluid Approximation for Warm Dark Matter
The episode details the paper 'Analytic Fluid Approximation for Warm Dark Matter.' The authors introduce a fast and highly accurate analytical method that models WDM particles from relativistic to non-relativistic states. This approach allows researchers to derive specific constraints on WDM properties, yielding a lower bound of 0.3 eV, which is tested against data from the Planck CMB and WiggleZ surveys.
