 ![Dashed lines show the specific angular momentum as a function of time for the dark matter that, at $z=0$, lies within the virial radius of the system for NF (left panel) and E-0.0 (right panel). We also show with dots the specific angular momentum for the baryons which end up as cold gas or stars in the central $00\ h^{-0}$ kpc at $z=0$. The arrows show the specific angular momentum of disk and spheroid stars. []{data-label="j_evolution"}](fig0
