Benjamin has written an article entitled “Dark Chemistry or Psychic Spin Pixel?” which promotes a “dark chemistry” model of mind and discuss the spin-mediated theory. This hypothetical chemistry is ba...
High-redshift galaxies in cold dark matter models
dark matter large-scale structure of the Universe
2014/12/26
We use hydrodynamic cosmological simulations to predict the star formation properties of high-redshift galaxies (z = 2-6) in five variants of the inflationary cold dark matter scenario, paying particu...
Dark matter-wave solitons in the dimensionality crossover
Soliton statics dynamics and dimension crossover regime schrodinger mean-field model
2014/12/25
We consider the statics and dynamics of dark matter-wave solitons in the dimensionality crossover regime from three dimensions (3D) to one dimension (1D). There, using the nonpolynomial Schröding...
X-ray absorption by the low-redshift intergalactic medium: A numerical study of the Lambda cold dark matter model

Using a hydrodynamic simulation of a cold dark matter universe with a cosmological constant, we investigate the "X-ray forest" absorption imprinted on the spectra of background quasars by the interven...
Dark Matter Constraints from the Sagittarius Dwarf and Tail System
the Sagittarius Dwarf Tail System
2014/12/24
2MASS has provided a three-dimensional map of the >360 degree, wrapped tidal tails of the Sagittarius (Sgr) dwarf spheroidal galaxy, as traced by M giant stars. With the inclusion of radial velocity d...
The evolution of a stellar bar transforms not only the galactic disc, but also the host dark matter halo. We present high-resolution, fully self-consistent N-body simulations that clearly demonstrate ...

dark matter large-scale structure of the universe
2014/12/24
N-body simulations predict that cold dark matter (CDM) halo-assembly occurs in two phases: (i) a fast-accretion phase with a rapidly deepening potential well; and (ii) a slow-accretion phase character...
We consider the sensitivity of the circular-orbit adiabatic contraction approximation to the baryon condensation rate and the orbital structure of dark matter haloes in the Λ cold dark matter (ΛCDM) p...
