Axinos as Cold Dark Matter [PDF]

open access: yesAIP 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.

WISPy cold dark matter [PDF]

open access: yesJournal 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.

How cold is cold dark matter? [PDF]

open access: yesJournal 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.

Cold dark matter resuscitated? [PDF]

open access: yesMonthly 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.

Substructures in cold dark matter haloes [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2004
We analyse the properties of substructures within dark matter halos (subhalos) using a set of high-resolution numerical simulations of the formation of structure in a Lambda-CDM Universe. Our simulation set includes 11 high-resolution simulations of massive clusters as well as a region of mean density, allowing us to study the spatial and mass ...

Axions as hot and cold dark matter [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2014
The presence of a hot dark matter component has been hinted at 3 sigma by a combination of the results from different cosmological observations. We examine a possibility that pseudo Nambu-Goldstone bosons account for both hot and cold dark matter components.

Axino cold dark matter revisited [PDF]

open access: yesJournal of High Energy Physics, 2012
Abstract Axino arises in supersymmetric versions of axion models and is a natural candidate for cold or warm dark matter. Here we revisit axino dark matter produced thermally and non-thermally in light of recent developments. First we discuss the definition of axino relative to low energy axion one for several KSVZ and DFSZ models ...
