@article{Knebe2009ONTS, title={ON THE STARTING REDSHIFT COSMOLOGICAL SIMULATIONS: FOCUSING ON HALO PROPERTIES}, author={Alexander Knebe and Christian Wagner and Steffen R. Knollmann and Tobias Diekershoff and Fabian Krause}, journal={The Astrophysical Journal}, year={2009}, volume={698}, pages={266 - 274} }

We systematically study the effects of varying the starting redshift zi for cosmological simulations in the highly nonlinear regime. Our primary focus lies with the (individual) properties of dark matter halos—namely the mass, spin, triaxiality, and concentration—where we find that even substantial variations in zi leave only a small imprint, at least for the probed mass range M ∈ [1010, 1013] h−1 M☉ and when investigated at redshift z = 0. We further compare simulations started by using the…
