Journal ArticleDOI
Where are the missing galactic satellites
TL;DR: In this paper, the authors compare the observed and predicted VDFs cross at B50 km s~1, indicating that the predicted abundance of satellites with km s-1 V circ Z 50 is in reasonably good agreement with observations.
Journal ArticleDOI
Profiles of dark haloes: evolution, scatter and environment
James S. Bullock,James S. Bullock,Tsafrir S. Kolatt,Tsafrir S. Kolatt,Yair Sigad,Rachel S. Somerville,Rachel S. Somerville,Andrey V. Kravtsov,Andrey V. Kravtsov,Anatoly Klypin,Joel R. Primack,Avishai Dekel +11 more
TL;DR: In this paper, the authors studied the dark-matter halo density profiles in a high-resolution N-body simulation of a CDM cosmology and found that the redshift dependence of the median concentration is cvirRvir/rs.
Journal ArticleDOI
Toward a halo mass function for precision cosmology: The Limits of universality
Jeremy L. Tinker,Andrey V. Kravtsov,Anatoly Klypin,Kevork N. Abazajian,Michael S. Warren,Gustavo Yepes,Stefan Gottlöber,Daniel E. Holz +7 more
TL;DR: In this paper, the mass function of dark matter halos is measured in a large set of collisionless cosmological simulations of flat ΛCDM cosmology and investigated its evolution at -->z 2.5.
Journal ArticleDOI
Erratum: "Chandra Sample of Nearby Relaxed Galaxy Clusters: Mass, Gas Fraction, and Mass-Temperature Relation"
Alexey Vikhlinin,Andrey V. Kravtsov,William R. Forman,C. Jones,Maxim Markevitch,S. S. Murray,L. van Speybroeck +6 more
TL;DR: In this paper, gas and total mass profiles for 13 low-redshift, relaxed clusters spanning a temperature range 0.7-9 keV were derived from all available Chandra data of sufficient quality.
