Manoj Kaplinghat studies connections between particle, dark matter and astronomical structure. The research programme described by his institution uses gravitational lensing and stellar motions to investigate matter distributions in galaxies and clusters.[ref]
Dark matter, Gravitational lensing by University of California, Irvine. Research description: lensing, dwarf-galaxy kinematics and particle properties
These measurements connect microscopic matter models with macroscopic dynamics. Inferring a particle's properties requires more than estimating total mass: the spatial distribution, velocities and possible interactions must also be consistent with the observations.
