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.

The Epoch of Reionization in Warm Dark Matter Scenarios [PDF]
Universe, 2021 In this paper we investigate how the Reionization process is affected by early galaxy formation in different cosmological scenarios. We use a semi-analytic model with suppressed initial power spectra to obtain the UV Luminosity Function in thermal Warm ...

Warm Dark Matter in Simulations [PDF]
Universe, 2022 In recent years, warm dark matter models have been studied as a viable alternative to the cold dark matter models. The warm dark matter particle properties are expected to imprint distinct signatures on the structure formation at both large and small ...

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.

WARM DARK MATTER MODEL OF GALAXY FORMATION [PDF]
Modern Physics Letters A, 2001 Cold Dark Matter (CDM) models of galaxy formation had been remarkably successful to explain a number of observations in the past decade. However, with both the theoretical modeling and the observations being improved, CDM models have been very recently shown to have excessive clustering on the sub-galactic scale.

Decaying warm dark matter revisited [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 AbstractDecaying dark matter models provide a physically motivated way of channeling energy between the matter and radiation sectors. In principle, this could affect the predicted value of the Hubble constant in such a way as to accommodate the discrepancies between CMB inferences and local measurements of the same.

Decaying Warm Dark Matter and Neutrino Masses [PDF]
Physical Review Letters, 2007 Neutrino masses may arise from spontaneous breaking of ungauged lepton number. Due to quantum gravity effects the associated Goldstone boson - the majoron - will pick up a mass. We determine the lifetime and mass required by cosmic microwave background observations so that the massive majoron provides the observed dark matter of the Universe.

Primordial black-hole dark matter via warm natural inflation
Physics Letters B, 2022 We report on a study of the natural warm inflationary paradigm (WNI). We show two important new results arise in this model. One is that the observational constraints on the primordial power spectrum from the cosmic microwave background (CMB) can be ...

Constraints on Warm Dark Matter from Cosmological Reionization [PDF]
, 2001 We study the constraints that high-redshift structure formation in the universe places on warm dark matter (WDM) dominated cosmological models. We modify the extended Press-Schechter formalism to derive the halo mass function in WDM models.

Warm dark matter versus bumpy power spectra [PDF]
, 2003 In this paper we are exploring the differences between a Warm Dark Matter model and a CDM model where the power on a certain scale is reduced by introducing a narrow negative feature ("dip").
