Group Identification in N-Body Simulations: SKID and DENMAX Versus Friends-of-Friends
M. Goetz, J. P. Huchra, R. H. Brandenberger
Three popular algorithms (FOF, DENMAX, and SKID) to identify halos in cosmological N-body simulations are compared with each other and with the predicted mass function from Press-S…
