Toward a Halo Mass Function for Precision Cosmology: The Limits of Universality
We measure the mass function of dark matter halos in a large set of collisionless cosmological simulations of flat ΛCDM cosmology and investigate its evolution at z≲ 2. Halos are identified as…

MultiDark simulations: the story of dark matter halo concentrations and density profiles
Accurately predicting structural properties of dark matter halos is one of the fundamental goals of modern cosmology. We use the new suite of MultiDark cosmological simulations to study the evolution…

THE LARGE-SCALE BIAS OF DARK MATTER HALOS: NUMERICAL CALIBRATION AND MODEL TESTS
We measure the clustering of dark matter halos in a large set of collisionless cosmological simulations of the flat ΛCDM cosmology. Halos are identified using the spherical overdensity algorithm,…

The Santa Barbara Cluster Comparison Project: A Comparison of Cosmological Hydrodynamics Solutions
We have simulated the formation of an X-ray cluster in a cold dark matter universe using 12 different codes. The codes span the range of numerical techniques and implementations currently in use,…

On the physical origin of dark matter density profiles
The radial mass distribution of dark matter haloes is investigated within the framework of the spherical infall model. We present a new formulation of spherical collapse including non-radial motions,…

Redshift-Space Clustering of SDSS Galaxies — Luminosity Dependence, Halo Occupation Distribution, and Velocity Bias
We present the measurements and modelling of the small-to-intermediate scale (� 0.1‐ 25h 1 Mpc) projected and three-dimensional (3D) redshift-space two-point correlation functions (2PCFs) of local…

Hydrodynamical simulations of galaxy formation: effects of supernova feedback
We numerically simulate some of the most critical physical processes in galaxy formation: The supernova feedback, in conjunction with gasdynamics and gravity, plays a crucial role in determining how…

Dwarf galaxies in voids: suppressing star formation with photoheating
We study the structure formation in cosmological void regions using high-resolution hydrody-namical simulations. Despite being significantly underdense, voids are populated abundantly with small dark…
