We study resolution effects in numerical simulations of gas -rich and gas-poor major mergers, and show that the formation of slowly-rotating ellipti cal galaxies often requires a resolution that is beyond the present-day standards to be properly modelled. Our sample of equalmass merger models encompasses various masses and spatial r esolutions, ranging from about 200 pc and10 particles per component (stars, gas and dark matter), i.e. a gas mass resolution of ∼ 10 M⊙, typical of some recently… CONTINUE READING
