Neutralino Warm Dark Matter [PDF]
Physics Letters B, 2000 In the supersymmetric (SUSY) standard model, the lightest neutralino may be the lightest SUSY particle (LSP), and it is is a candidate of the dark matter in the universe.

Massive sterile neutrinos as warm Dark Matter [PDF]
Astroparticle Physics, 2000 We show that massive sterile neutrinos mixed with the ordinary ones may be produced in the early universe in the right amount to be natural warm dark matter particles.

Hot QCD and warm dark matter [PDF]
Proceedings of XXIVth International Symposium on Lattice Field Theory — PoS(LAT2006), 2006 One of the possible explanations for the dark matter needed in the standard cosmological model is so-called warm dark matter, in the form of right-handed ("sterile") neutrinos with a mass in the keV range.

Dark Matter Halo Merger Histories Beyond Cold Dark Matter: I - Methods and Application to Warm Dark Matter [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 We describe a methodology to accurately compute halo mass functions, progenitor mass functions, merger rates and merger trees in non-cold dark matter universes using a self-consistent treatment of the generalized extended Press-Schechter formalism.

Cores and cusps in warm dark matter halos [PDF]
Journal of Cosmology and Astroparticle Physics, 2011 The apparent presence of large core radii in Low Surface Brightness galaxies has been claimed as evidence in favor of warm dark matter. Here we show that WDM halos do not have cores that are large fractions of the halo size: typically, r_core/r_200 < 0.001.

Common origin of warm dark matter and dark radiation [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We consider a cosmological scenario where a relativistic particle and a stable massive particle are simultaneously produced from the decay of a late-decaying particle after Big-Bang Nucleosynthesis but before matter-radiation equality. The relativistic and massive particles behave as dark radiation and warm dark matter, respectively.

REIONIZATION IN THE WARM DARK MATTER MODEL [PDF]
The Astrophysical Journal, 2012 Compared with the cold dark matter (CDM) model, in the warm dark matter (WDM) model formation of small scale structure is suppressed. It is often thought that this would delay the reionization of the intergalactic medium (IGM), as the star formation rate during the epoch of reionization (EOR) would be lowered. However, during the later stage of the EOR,
