Abstract: We describe a new algorithm discussed in Elahi et al. (2011) designed to find substructures within dark matter haloes from N-body simulations. The algorithm relies upon the fact that substructures in a halo will have a local velocity distribution that differs significantly from the smooth background halo. We apply our algorithm to several test cases and show that it identifies not only subhaloes, but can recover tidal streams with a high purity.
