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...
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...
