The work shows that free-streaming dark radiation isocurvature produces a qualitatively different gravitational wave spectrum than cold dark matter isocurvature and derives constraints on isocurvature power spectra around 10^6 Mpc^{-1} from NANOGrav data.

Including neutrino density isocurvature in fits to ACT DR6, DESI DR2, and DES data yields ∑m_ν < 0.057 eV at 95% CL in ΛCDM with no detection of the isocurvature mode.

Including neutrino density isocurvature in fits to ACT DR6, DESI DR2, and DES data yields ∑m_ν < 0.057 eV at 95% CL in ΛCDM with no detection of the isocurvature mode.
