Angular momentum evolution in dark matter haloes: a study of the Bolshoi and Millennium simulations

Abstract We use three different cosmological dark matter simulations to study how the orientation of the angular momentum (AM) vector in dark matter haloes evolve with time. We find that haloes in this kind of simulations are constantly affected by a spurious change of mass, which translates into an...
