- Abstract
- More than five-sixths of the matter in the universe is dark matter, a substance which cannot be seen and which interacts with other particles almost entirely through gravity. The identity of the dark matter is a longstanding open question. A class of models known as scalar field dark matter (SFDM) are exciting dark matter candidates that share common properties including the formation of solitons in the cores of dark matter halos. Solitons are energetically stable, gravitationally bound states of an extremely large number of SFDM particles that are the solutions to the classical equations of motion for SFDM, and in this work we present results of studies into their properties. We investigate the ability of solitons to emerge from virialized initial conditions in dark matter halos through kinetic relaxation and calculate the timescales associated with this process. We simulate rotating solitons which develop a unique vortex structure and study conditions under which the vortices can remain stable. We also explore models of SFDM which are expanded to include multiple species with both gravitational and non-gravitational inter-species interactions.
