Simulating Coulomb Interacting Dark Matter

Abstract

While Dark Matter (DM) is known to be the dominant form of matter in the universe through its gravitational effects on visible matter, the microscopic properties of DM are unknown. Astronomical observations and direct detection experiments suggest that DM may have selfinteractions. We propose a numerical simulation of the cosmological formation of DM halos under the influence of Newtonian gravity and Coulomb-like self-interactions.
