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 ...

Cold dark matter: Controversies on small scales [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 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.

Cold dark matter with MOND scaling
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2010 We provide a holographic dual description of Milgrom's scaling associated with galactic rotation curves. Our argument is based on the recent entropic reinterpretation of Newton's laws of motion. We propose a duality between cold dark matter and modified Newtonian dynamics (MOND).

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

Cold Dark Matter and Neutralinos [PDF]
Nuclear Physics B - Proceedings Supplements, 2002 Neutralinos are natural candidates for cold dark matter in many realizations of supersymmetry. We briefly review our recent results in the evaluation of neutralino relic abundance and direct detection rates in a class of supergravity models.Comment: 4 ...

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.

Condensation of Galactic Cold Dark Matter
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 ...

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.
