Abstract

The core-cusp problem refers to the inconsistency between simulations of the theory of cold dark matter and observations of dwarf galaxies. Specifically, the disagreement of the dark matter density profiles at the center of these galaxies. Fuzzy dark matter is thought to rectify this disparity. To test the validity of this theory, we used the Klein-Gordon equation for general relativity and derive its non-relativistic limit coupled to gravity. Numerical integration was used to solve this equation of motion for dark matter and the soliton is compared to data from THINGS and theoretical profiles. Analyzing these density profiles allows us to judge the validity of the fuzzy dark matter model.

Explaining Galactic Halos with Fuzzy Dark Matter
