- Cold dark matter - Cold dark matter (or CDM) is a refinement of the big bang theory that contains the additional assumption that most of the matter in the Universe consists of material that cannot be observed by its electromagnetic radiation and hence is dark while at the same time the particles making up ...
- Warm dark matter - Warm dark matter (WDM) is theorized to have properties which are intermediate between those of hot dark matter and cold dark matter. WDM particles are often typified by sterile neutrinos.
- Cryogenic Dark Matter Search - The Cryogenic Dark Matter Search (CDMS) is an experiment designed to directly detect particle dark matter in the form of WIMPs. Using an array of semiconductor detectors at millikelvin temperatures, CDMS has set the most sensitive limits to date on the interactions of WIMP dark matter with terrestrial materials.
- Hot dark matter - Hot dark matter is a form of dark matter which consists of particles that travel with ultrarelativistic velocities. The best candidate for the identity of hot dark matter is the neutrino.
- Self-interacting dark matter - In astrophysics self-interacting dark matter is a hypothetical form of dark matter consisting of particles with strong self-interactions. This type of dark matter was postulated to resolve a number of conflicts between observations and simulations on the galactic scale and smaller.
