Warm dark matter primordial spectra and the onset of structure formation at redshift z
, 2013 Analytic formulas reproducing the warm dark matter (WDM) primordial spectra are obtained for WDM particles decoupling in and out of thermal equilibrium which provide the initial data for WDM non-linear structure formation.

MaGICC-WDM: the effects of warm dark matter in hydrodynamical simulations of disc galaxy formation
, 2013 We study the effect of warm dark matter (WDM) on hydrodynamic simulations of galaxy formation as part of the Making Galaxies in a Cosmological Context (MaGICC) project. We simulate three different galaxies using three WDM candidates of 1, 2 and 5 keV and

The Asymptotic Form of Cosmic Structure: Small Scale Power and Accretion History [PDF]
, 2006 We explore the effects of small scale structure on the formation and equilibrium of dark matter halos in a universe dominated by vacuum energy. We present the results of a suite of four N-body simulations, two with a LCDM initial power spectrum and two ...

Quantum WDM fermions and gravitation determine the observed galaxy structures
, 2013 Quantum mechanics is necessary to compute galaxy structures at kpc scales and below. This is so because near the galaxy center, at scales below 10 - 100 pc, warm dark matter (WDM) quantum effects are important: observations show that the interparticle ...
