Non-Cold Dark Matter from Primordial Black Hole Evaporation
, 2020 Dark matter coupled solely gravitationally can be produced through the decay of primordial black holes in the early universe. If the dark matter is lighter than the initial black hole temperature, it could be warm enough to be subject to structure ...

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.

Cutoff in the Lyman-α forest power spectrum: Warm IGM or warm dark matter?
Physics Letters B, 2017 We re-analyse high redshift and high resolution Lyman-α forest spectra considered in [1], seeking to constrain the properties of warm dark matter particles.

Comments on Warm Dark Matter Measurements and Limits
International Journal of Astronomy and Astrophysics International Journal of Astronomy and Astrophysics, 2022 Observed spiral galaxy rotation curves allow a measurement of the warm dark matter particle velocity dispersion and mass. The measured thermal relic mass 100 h m ≈ eV is in disagreement with limits, typically in the range 1 to 4 keV.

Dark Matters on the Scale of Galaxies
Universe, 2020 The cold dark-matter model successfully explains both the emergence and evolution of cosmic structures on large scales and, when we include a cosmological constant, the properties of the homogeneous and isotropic Universe.

Constraints on dark-matter properties from large-scale structure [PDF]
, 2016 We use large-scale cosmological observations to place constraints on the dark-matter pressure, sound speed and viscosity, and infer a limit on the mass of warm-dark-matter particles.

Gamma-rays From Warm WIMP Dark Matter Annihilation
, 2012 The weakly interacting massive particle (WIMP) often serves as a candidate for the cold dark matter, however when produced non-thermally it could behave like warm dark matter.
