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).

Cold Particle Dark Matter [PDF]
Symmetry, 2021 Possible dark matter candidates in particle physics span a mass range extending over fifty orders of magnitude. In this review, we consider the range of masses from a few keV to a few hundred TeV, which is relevant for cold particle dark matter. We will consider models where dark matter arises as weakly coupled elementary fields and models where dark ...

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 Lensing as a Probe of Cold Dark Matter Subhalos [PDF]
Advances in Astronomy, 2010 In the cold dark matter scenario, dark matter halos are assembled hierarchically from smaller subunits. Some of these subunits are disrupted during the merging process, whereas others survive temporarily in the form of subhalos.

Axino cold dark matter revisited [PDF]
Journal 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 ...
