dc.descriptionWe present results from a Smoothed Particle Hydrodynamic (SPH) simulation of galaxy formation that exceeds the minimum resolution requirement suggested by Steinmetz & Muller (1993) of 3*10^4 SPH particles per galaxy. Using the multiple mass technique an effective resolution of a little over one billion particles is attained within a 48 Mpc cube. We find that even with an SPH mass resolution of 1.5*10^6 solar masses and a plausible feedback algorithm, the cooling catastrophe continues to be a problem for Einstein-de Sitter CDM cosmologies. Increasing resolution also appears to exacerbate the core-halo angular momentum transport problem.
