Research involves

Understanding the particle dynamics of dark matter, from its role in galaxies to its discovery in the laboratory.

Research relevance

This research seeks to discover the unknown particle physics of dark matter, the dominant form of matter in the Universe.

Research summary

Dark matter is the unknown mass that makes up the cosmic foundation of the Universe. This research in theoretical physics will explore how dark matter’s microscopic particle dynamics can shape the structure of galaxies and other astronomical observables. Observations, in turn, will be used to constrain and determine dark matter’s unknown properties. Questions to be addressed include: Do dark matter particles interact with one another through any forces beyond gravity? If so,what types of forces are allowed when confronted with observations spanning the smallest galaxies to the large scale structure of the Universe?
