The shape of dark matter halos: A new fundamental cosmological invariance

Median prolaticity as a function of log $σ_{N L}^{- 1}$ $\[\sigma_{N L}^{-1}\]$ . The curves corresponding to the different cosmological models superpose, as they did when binning in $\log σ_{N L, I H}^{- 1}$ $\[\log ~\sigma_{N L, I H}^{-1}\]$ . This suggests the existence of a cosmological independent mapping between variances of total and in-halo nonlinear power spectra.
