The central slope of dark matter cores in dwarf galaxies: Simulations vs. THINGS
Galaxies dark matter halos – galaxies cosmological N-body+SPH simulations –galaxies kinematics and dynamics
2010/11/15
We make a direct comparison of the derived dark matter (DM) distributions between hydrody-
namical simulations of dwarf galaxies assuming a CDM cosmology and the observed dwarf galaxies sample from ...
Warm dark matter at small scales: peculiar velocities and phase space density
Warm dark matter small scales peculiar velocities phase space density
2010/11/12
We study the scale and redshift dependence of the power spectra for density perturbations and
peculiar velocities, and the evolution of a coarse grained phase space density for (WDM) particles that d...
Spin and spin-isospin instabilities in asymmetric nuclear matter at zero and finite temperatures using Skyrme functionals
Spin spin-isospin instabilities asymmetric nuclear matter at zero finite temperatures
2010/11/16
Self-consistent mean field methods based on phenomenological Skyrme effective interactions are
known to exhibit spurious spin and spin-isospin instabilities both at zero and finite temperatures when ...
If the dark matter of our galaxy is composed of nuggets of quarks or antiquarks in a colour superconducting phase there will be a small but non-zero ux of these objects through the Earth's atmosphere.
Cores and Cusps in Warm Dark Matter Halos
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
The apparent presence of large core radii in Low Surface Brightness galaxies has been claimed as evidence in favor of warm dark matter. Here we show that WDM halos do not have cores that are large fra...
We consider new signatures of WIMPless dark matter, particularly those which can be used to test models with low dark matter mass. We focus on detection prospects at hadron colliders through the produ...
