Observational evidence and theoretical arguments indicate that most of the universe is made of dark matter. Supersymmetry, an extension of the standard model of particle interactions, provides a natural candidate for dark ...

Fritz Zwicky is identified commonly as the discoverer of dark matter, the unobservable mass that is believed to occupy about 90 percent of the universe. In 1933 Zwicky found a mass discrepancy in the Coma cluster of galaxies, ...

We describe a new algorithm for finding substructures within dark matter haloes from N-body simulations. The algorithm relies upon the fact that dynamically distinct substructures in a halo will have a local velocity ...
