Cold dark matter (CDM) as a research area encompasses theoretical, computational, and observational studies of non-relativistic, weakly interacting matter that dominates the matter density of the Universe and seeds structure formation. Research focuses on modeling CDM’s impact on cosmic microwave background anisotropies, large-scale structure, galaxy and cluster halos, and substructure through N-body simulations and analytic frameworks such as linear perturbation theory and halo models. It also investigates constraints from gravitational lensing, galaxy dynamics, and cosmological surveys, and explores candidate particle properties via indirect astrophysical signatures and their consistency with precision cosmology and alternative dark matter scenarios.
Published in Nature, scientists at King's College London, Harvard University, UC Berkeley and others have shared the foundation of what they believe will be the most accurate dark matter detector to date.
