Cores in dwarf galaxies from dark matter with a Yukawa potential.
We show that cold dark matter particles interacting through a Yukawa potential could naturally explain the recently observed cores in dwarf galaxies without affecting the dynamics of objects with a much larger velocity dispersion, such as clusters of galaxies. The velocity dependence of the associated cross section as well as the possible exothermic nature of the interaction alleviates earlier ...
متن کاملOn the Origin of Dark Matter Cores in Dwarf Galaxies
In this paper, we study the dynamical stability and time evolution of the central dark matter cores of low-mass (about 10 − 109M⊙) galactic haloes found in recent cold dark matter simulations at high redshift. From those simulations we extract three haloes, assembled by hierarchical merging, that at redshift z > ∼ 10 display a core and we evolve them without further merging to low redshift usin...
متن کاملDark matter distribution in dwarf spheroidal galaxies
We present predictions for the line-of-sight velocity dispersion profiles of dwarf spheroidal galaxies and compare them to observations in the case of the Fornax and Draco dwarfs. The predictions are made in the framework of standard dynamical theory of two-component (stars and dark matter) spherical systems with different velocity distributions. The stars are assumed to be distributed accordin...
متن کاملDark Matter in Dwarf Galaxies: The First Dark Galaxy?
We present new H i observations of the high-velocity cloud (HVC) that we resolved near the Local Group dwarf galaxy LGS 3. The cloud is rotating, with an implied mass that makes it dark matter-dominated no matter what its distance from the Milky Way is. Our new, high-sensitivity Arecibo observations demonstrate that the faint H i features that we previously described as tidal tails are indeed r...
متن کاملA Model for Dwarf Spheroidal Satellite Galaxies Without Dark Matter
Self-consistent simulations of the dynamical evolution of low-mass satellite galaxies without dark matter on different orbits interacting with an extended Galactic dark halo are described. The calculations proceed for many orbital periods until well after the satellite dissolves. In all cases the dynamical evolution converges to a remnant that contains roughly 1 per cent of the initial satellit...
