The inner structure of CDM haloes -- I. A numerical convergence study
The inner structure of CDM haloes -- I. A numerical convergence study
We present a comprehensive set of convergence tests which explore the role of various numerical parameters on the equilibrium structure of a simulated dark matter halo. We report on results obtained with two independent, state-of-the-art, multi-stepping, parallel N-body codes: pkdgrav and gadget. We find that convergent mass profiles can be …
