Journal ArticleDOI
The mass-concentration-redshift relation of cold and warm dark matter haloes
Aaron D. Ludlow,Sownak Bose,Raul E. Angulo,Lan Wang,Wojciech A. Hellwing,Wojciech A. Hellwing,Wojciech A. Hellwing,Julio F. Navarro,Shaun Cole,Carlos S. Frenk +9 more
TL;DR: In this article, a suite of cosmological simulations were used to study the mass-concentration-redshift relation of dark matter haloes, and the mass profiles of CDM and WDM haloes were self-similar and well approximated by the Einasto profile.
Journal ArticleDOI
Universal structure of dark matter haloes over a mass range of 20 orders of magnitude.
Jie Wang,Sownak Bose,Carlos S. Frenk,Liang Gao,Adrian Jenkins,Volker Springel,Simon D. M. White +6 more
TL;DR: In this paper, a cosmological simulation of the formation of present-day haloes over the full range of observed halo masses (20 orders of magnitude) when dark matter is assumed to be in the form of weakly interacting massive particles of mass approximately 100 gigaelectronvolts.
Journal ArticleDOI
Modified gravity N-body code comparison project
Hans A. Winther,Fabian Schmidt,Alexandre Barreira,Christian Arnold,Christian Arnold,Sownak Bose,Claudio Llinares,Claudio Llinares,Marco Baldi,Marco Baldi,Bridget Falck,Wojciech A. Hellwing,Wojciech A. Hellwing,Kazuya Koyama,Baojiu Li,David F. Mota,Ewald Puchwein,Robert E. Smith,Gong-Bo Zhao,Gong-Bo Zhao +19 more
TL;DR: In this article, a detailed comparison of the results of different N-body codes for the f (R), Dvali-Gabadadze-Porrati and Symmetron models, starting from the same initial conditions, is provided.
Journal ArticleDOI
A Redshift-independent Efficiency Model: Star Formation and Stellar Masses in Dark Matter Halos at z ≳ 4
TL;DR: In this article, the authors explore the connection between the UV luminosity functions (LFs) of high-z$ galaxies and the distribution of stellar masses and star-formation histories (SFHs) in their host dark matter halos.
Journal ArticleDOI
The Copernicus Complexio: statistical properties of warm dark matter haloes
Sownak Bose,Wojciech A. Hellwing,Wojciech A. Hellwing,Carlos S. Frenk,Adrian Jenkins,Mark R. Lovell,Mark R. Lovell,John C. Helly,Baojiu Li +8 more
TL;DR: In this paper, the authors investigate the properties of dark matter haloes formed in a high-resolution cosmological N-body simulation from initial conditions similar to those expected in a universe in which the dark matter consists of 7 keV sterile neutrinos.
