The viability of ultralight bosonic dark matter in dwarf galaxies

Understand

The dark matter distribution in dwarf galaxies holds a wealth of information on the fundamental properties and interactions of the dark matter particle.

• In this paper, we study whether ultralight bosonic dark matter is consistent with the gravitational potential extracted from stellar kinematics.
• We use velocity dispersion measurements to constrain models for halo mass and particle mass.
• The posterior likelihood is multimodal.
