Holographic interacting dark energy in the braneworld cosmology
, 2007 We investigate a model of brane cosmology to find a unified description of the radiation-matter-dark energy universe. It is of the interacting holographic dark energy with a bulk-holographic matter $\chi$.

Observational evidence for self-interacting cold dark matter [PDF]
, 2000 Cosmological models with cold dark matter composed of weakly interacting particles predict overly dense cores in the centers of galaxies and clusters and an overly large number of halos within the Local Group compared to actual observations.

Bose-Einstein Condensation of Dark Matter Axions [PDF]
, 2009 We show that cold dark matter axions thermalize and form a Bose-Einstein condensate. We obtain the axion state in a homogeneous and isotropic universe, and derive the equations governing small axion perturbations.

Physics Letters B, 2014 In this paper, we study a cosmological model in general relativity within the framework of spatially flat Friedmann–Robertson–Walker space–time filled with ordinary matter (baryonic), radiation, dark matter and dark energy, where the latter two ...

The Impact Of Cold Dark Matter Variants On The Halos Of The First Stars And Galaxies: Angular Momentum And Vortex Creation In BEC Dark Matter [PDF]
, 2010 If cold dark matter elementary particles form a Bose-Einstein condensate, their superfluidity may distinguish them from other forms of cold dark matter, including the creation of quantum vortices.

Strangeness, cosmological cold dark matter and dark energy [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2005 It is now believed that the universe is composed of a small amount of the normal luminous matter, a substantial amount of matter (Cold Dark Matter: CDM) which is non-luminous and a large amount of smooth energy (Dark Energy: DE). Both CDM and DE seem to require ideas beyond the standard model of particle interactions.

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 ...

Closed-form Expressions for Multiscatter Dark Matter Capture Rates
The Astrophysical JournalAny astrophysical object can, in principle, serve as a probe of the interaction between dark matter (DM) and regular baryonic matter. This method is based on the potential observable consequences annihilations of captured DM have on the surface ...

The offsets between galaxies and their dark matter in Λ cold dark matter [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2015 Abstract We use the ‘Evolution and Assembly of GaLaxies and their Environments’ (eagle) suite of hydrodynamical cosmological simulations to measure offsets between the centres of stellar and dark matter components of galaxies. We find that the vast majority (>95 per cent) of the simulated galaxies display an offset smaller than ...
