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.

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: Controversies on small scales. [PDF]
Proc Natl Acad Sci U S A, 2015 The cold dark matter (CDM) cosmological model has been remarkably successful in explaining cosmic structure over an enormous span of redshift, but it has faced persistent challenges from observations that probe the innermost regions of dark matter halos and the properties of the Milky Way’s dwarf galaxy satellites.

Detecting cold dark-matter candidates [PDF]
Physical Review D, 1986 We consider the use of superheated superconducting colloids as detectors of weakly interacting galactic halo candidate particles (e.g. photinos, massive neutrinos, and scalar neutrinos). These low temperature detectors are sensitive to the deposition of a few hundreds of eV's.

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.

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.
