Strong Redshift Evolution of Non-Gaussian Vorticity in Galaxy Velocity Fields: Possible Bispectral Evidence for Beyond-ΛCDM Physics from 2.8M SDSS and DESI Galaxies.

This complementary analysis determines the critical mass threshold (Mc) for the 

detection of primordial vorticity and validates, using the Faber-Jackson relation, that the

detected signal cannot be attributed to internal astrophysical eects. We identify Mc ≈ 

3 × 1013M⊙ (Vdisp ≈ 200 km/s) as the lower limit for the emergence of vorticity, with 

bispectrum evolution of 11.22× and a signicance of > 17σ vs ΛCDM.
