TL;DR: In this article, the authors measure the clustering of dark matter halos in a large set of collisionless cosmological simulations of the flatCDM cosmology, and find that the bias of rare halos is higher than that predicted in the modified ellipsoidal collapse model of Sheth, Mo, & Tormen (2001), and approaches the predictions of the spherical collapse model for the rarest halos.

TL;DR: In this article, the authors analyzed the halo occupation distribution, the probability for a halo of mass M to host a number of subhalos N, and two-point correlation function of galaxy-size dark matter halos using high-resolution dissipationless simulations of the concordance flat LCDM model.

TL;DR: In this article, the authors apply standard disk formation theory with adiabatic contraction within cuspy halo models predicted by the standard cold dark matter (?CDM) cosmology.

TL;DR: In this paper, the authors present a new high-resolution N-body algorithm for cosmological simulations, which employs a traditional particle-mesh technique on a cubic grid and successive multilevel relaxations on the finer meshes, introduced recursively in a fully adaptive manner in the regions where the density exceeds a predefined threshold.

TL;DR: In this paper, the authors analyzed the dynamical evolution of the substructure halos in a high-resolution cosmological simulation of Milky Way-sized halos, in a hierarchical cold dark matter (CDM) cosmology.
