How cold is cold dark matter? [PDF]
Journal of Cosmology and Astroparticle Physics, 2013 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 ...

Brief History of Ultra-light Scalar Dark Matter Models [PDF]
EPJ Web of Conferences, 2018 This is a review on the brief history of the scalar field dark matter model also known as fuzzy dark matter, BEC dark matter, wave dark matter, or ultra-light axion. In this model ultra-light scalar dark matter particles with mass m = O(10-22)eV condense

Science, 1996 Motivated by inflation, the theory of big-bang nucleosynthesis and the quest for a deeper understanding of the fundamental forces and particles, a very successful paradigm for the development of structure in the Universe has evolved.

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.

Gravitational waves in cold dark matter [PDF]
Physical Review D, 2018 We study the effects of cold dark matter on the propagation of gravitational waves of astrophysical and primordial origin. We show that the dominant effect of cold dark matter on gravitational waves from astrophysical sources is a small frequency ...

Condensation of Galactic Cold Dark Matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2016 We consider the steady-state regime describing the density profile of a dark matter halo, if dark matter is treated as a Bose-Einstein condensate. We first solve the fluid equation for "canonical" cold dark matter, obtaining a class of density profiles ...

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 ...

The Structure of cold dark matter halos [PDF]
The Astrophysical Journal, 1995 High resolution N-body simulations show that the density profiles of dark matter halos formed in the standard CDM cosmogony can be fit accurately by scaling a simple “universal” profile.

Cold dark matter heats up [PDF]
Nature, 2014 A principal discovery in modern cosmology is that standard model particles comprise only 5 per cent of the mass-energy budget of the Universe. In the ΛCDM paradigm, the remaining 95 per cent consists of dark energy (Λ) and cold dark matter. ΛCDM is being

Hidden Hot Dark Matter as Cold Dark Matter [PDF]
, 2009 We show that hidden hot dark matter, hidden-sector dark matter with interactions that decouple when it is relativistic, is a viable dark matter candidate provided it has never been in thermal equilibrium with the particles of the standard model.
