Combined HSC, Planck, ACT, and DESI data prefer a rapid late-time suppression of structure growth at roughly 2 sigma over LambdaCDM and baryonic or neutrino alternatives.
For the fiducialΛCDM model, we assumeM ν = 0.06eV for the total neutrino mass, corresponding to the lower bound of the normal mass hierarchy [e.g., 33]

Late-time suppression of structure growth as a solution for the $S_8$ tension
Combined HSC, Planck, ACT, and DESI data prefer a rapid late-time suppression of structure growth at roughly 2 sigma over LambdaCDM and baryonic or neutrino alternatives.
