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.
Australian researchers have played a central role in a landmark result from the LUX-ZEPLIN (LZ) experiment in South Dakota—the world's most sensitive dark matter detector. Today, scientists working on the experiment report ...

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is estimated to account for most of the universe's mass. Over the past decades, many physicists worldwide have been trying to detect ...
A new study by researchers at the University of Amsterdam shows how gravitational waves from black holes can be used to reveal the presence of dark matter and help determine its properties. The key is a new model, based on ...

What if I told you that while you can't see dark matter, maybe you can hear it? I know, I know, it sounds crazy…and it is crazy. But it's crazy enough that it just might work. It's a real life experiment, called the…let me ...

Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move through space at nearly ...
