The Large Underground Xenon experiment (LUX) aimed to directly detect weakly interacting massive particle (WIMP) dark matter interactions with ordinary matter on Earth. . Despite the wealth of (gravitational) evidence supporting the existence of non-baryonic dark matter in the Universe, [1] dark matter particles in our galaxy have never been directly detected in an expe
The DarkSide collaboration is an international affiliation of universities and labs seeking to directly detect dark matter in the form of weakly interacting massive particles (WIMPs). The collaboration is planning, building and operating a series of liquid argon time projection chambers (TPCs) that are employed at the Gran Sasso National ...
The primary dark matter candidate in the range are axions, or axion-like particles. From about 1 eV to the Planck Mass, dark matter is projected to be fermionic or particle-like. Favorites in this range include WIMPS, thermal relics, and sterile neutrinos. Finally, in the mass range between the Planck Mass to masses on the order of the Solar ...
In astronomy, dark matter is an invisible and hypothetical form of matter that does not interact with light or other electromagnetic radiation.Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be observed.
An ultra diffuse galaxy (UDG), or dark galaxy, [1] is an extremely low luminosity galaxy, the first example of which was discovered in the nearby Virgo Cluster by Allan Sandage and Bruno Binggeli in 1984. [a] These galaxies have been studied for many years prior to their renaming in 2015. Their lack of luminosity is due to the lack of star ...
It has been proposed that the galaxy contains little or no dark matter, the first such discovery. On 20 March 2019, a follow-up study announcing the discovery of a second UDG lacking dark matter, NGC 1052-DF4, was published. [5] NGC 1052-DF2 is located in the constellation Cetus, near the border with Eridanus.
States of matter that are not commonly encountered, such as Bose–Einstein condensates, fermionic condensates, nuclear matter, quantum spin liquid, string-net liquid, supercritical fluid, color-glass condensate, quark–gluon plasma, Rydberg matter, Rydberg polaron, photonic matter, Wigner crystal, [1] Superfluid and time crystal but whose ...
Dark matter is believed to dominate the gravitational potential of galaxies and clusters of galaxies. Under this theory, galaxies are baryonic condensations of stars and gas (namely hydrogen and helium) that lie at the centers of much larger haloes of dark matter, affected by a gravitational instability caused by primordial density fluctuations.
