Dependence of the other halo shape parameters on cosmology and halo mass. The halos of cosmological models with a lower σ₈ that have collapsed more recently are less spherical. Upper-left panel: median middle-to-major axis ratio versus halo mass. Upper-right panel: median triaxiality versus halo mass. Lower-left panel: median minor-to-major axis ratio versus halo mass. Lower-right panel: median ellipticity versus halo mass.
