DESI DR1 full-shape clustering yields Ω_m = 0.2962 ± 0.0095 and σ_8 = 0.842 ± 0.034 in flat ΛCDM, tightening to H_0 = 68.40 ± 0.27 km/s/Mpc with CMB and DESY3, while favoring w_0 > -1, w_a < 0 and limiting neutrino mass sum to < 0.071 eV.

Matter modeled as stochastic sources induces stochastic noise and new interactions in the large-scale EFT for light scalars, yielding corrections to the Klein-Gordon equation that can mimic dynamical dark energy or produce a cosmic Meissner effect under full screening.
MUST is a planned 6.5m Stage-V spectroscopic survey telescope targeting 100M+ galaxies and quasars to z~5.5 for large-scale structure cosmology studies.
