On the redshift evolution of the spin parameter in cosmological simulations
Tomas Riera, Alexander Knebe, Chris Power +2
Although the spin parameter of dark matter halos is well known to follow a log-normal distribution at fixed epoch, its quantitative redshift evolution - encompassing both the mean…

Tidal adaptive softening and artificial fragmentation in cosmological simulations
Robert A. Mostoghiu Paun, Darren Croton, Chris Power +3
Traditional N-body methods introduce localised perturbations in the gravitational forces governing their evolution. These perturbations lead to an artificial fragmentation in the f…
