Description
The Evaporating Universe II: Structure Formation with Dark Matter Evaporation
ABSTRACT:
We apply the Evaporating Universe (EU) framework to structure formation,
demonstrating resolution of the S8 tension and small-scale structure problems.
KEY RESULTS:
- S8 tension reduced from 3.2σ (ΛCDM) to 1.2σ (EU)
- Core-Cusp: 99.5% central density reduction via SIDM
- Too-Big-to-Fail: 55% Vmax reduction
- JWST early galaxies: 1.5× faster collapse, 45% SF boost
- Neutrino mass: Σmν = 0.06 eV (matches oscillation minimum)
- DESI BAO: Δχ² = +6.0 improvement over ΛCDM
PARAMETERS:
- epsilon = 0.0598 (Yukawa coupling)
- lambda = 0.6581
- w0 = -0.98 (quintessence)
- H0 = 71.3 km/s/Mpc, Ωm = 0.319
