Scientists propose a new method to search for dark matter using LIGO
A new study published in Physical Review Letters (PRL) proposes using gravitational wave detectors like LIGO to search for scalar field dark matter.
Page 8: Research news on Cold dark matter
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.
Pioneering research suggests nature of dark matter is more elusive than ever

A higher-dimensional model can help explain cosmic acceleration without dark energy
Dark energy remains among the greatest puzzles in our understanding of the cosmos. In the standard model of cosmology called the Lambda-CDM, it is accounted for by adding a cosmological constant term in Einstein's field equation ...
Searching for dark matter with the coldest quantum detectors in the world
One of the greatest mysteries of science could be one step closer to being solved. Approximately 80% of the matter in the universe is dark, meaning that it cannot be seen. In fact, dark matter is passing through us constantly—possibly ...
