Non-universality of dark-matter halos: cusps, cores, and the central potential

Jens Hjorth, Liliya L. R. Williams, Radosław Wojtak +1

Dark-matter halos grown in cosmological simulations appear to have central NFW-like density cusps with mean values of $d\log \rho /d\log r\approx -1$, and some dispersion, which is gen…
