How cold is cold dark matter? [PDF]
Journal of Cosmology and Astroparticle Physics, 2014 If cold dark matter consists of particles, these must be non-interacting and non-relativistic by definition. In most cold dark matter models however, dark matter particles inherit a non-vanishing velocity dispersion from interactions in the early universe, a velocity that redshifts with cosmic expansion but certainly remains non-zero.

CAUSTICS AND COLD DARK MATTER [PDF]
The Identification of Dark Matter, 2001 The hierarchical cold dark matter (CDM) model for structure formation is a well defined and testable model. Direct detection is the best technique for confirming the model yet predictions for the energy and density distribution of particles on earth remain inadequate.

Axinos as Cold Dark Matter [PDF]
AIP Conference Proceedings, 2006 The connection of Dark Matter to our particle physics model is still one of the open cosmological questions. In these proceedings I will argue that axinos can be successful Cold Dark Matter candidates in models with Supersymmetry and the Peccei-Quinn solution of the strong CP problem.

Journal of Cosmology and Astroparticle Physics, 2012 Very weakly interacting slim particles (WISPs), such as axion-like particles (ALPs) or hidden photons (HPs), may be non-thermally produced via the misalignment mechanism in the early universe and survive as a cold dark matter population until today.

The Cusp–Core Problem in Gas-Poor Dwarf Spheroidal Galaxies
Galaxies, 2021 This review deals with the inconsistency of inner dark matter density profiles in dwarf galaxies, known as the cusp–core problem. In particular, we aim to focus on gas-poor dwarf galaxies.

Cold dark matter resuscitated? [PDF]
Monthly Notices of the Royal Astronomical Society, 1995 The Cold Dark Matter (CDM) model has an elegant simplicitly which makes it very predictive, but when its parameters are fixed at their `canonical' values its predictions are in conflict with observational data. There is, however, much leeway in the initial conditions within the CDM framework.

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.

Making (dark matter) waves: Untangling wave interference for multi-streaming dark matter
The Open Journal of Astrophysics, 2022 The classical dynamics of collisionless cold dark matter, commonly described by fluid variables or a phase-space distribution, can be captured in a single semiclassical wavefunction.
