The Non-universal Pseudo Phase-Space Density Profiles of Symphony Host Halos

Bocheng Feng, Ethan O. Nadler, S. Peng Oh +1

Cosmological N-body simulations have long suggested that the pseudo phase-space density (PPSD), $\rho /{\sigma }^3$, of cold dark matter haloes follows the universal relation $ρ/σ^3 \propto r^…
