MultiDark
MultiDark (MULTImessenger Approach for DARK Matter Detection) is a Spanish project, with a stated goal of contributing to the identification and detection of dark matter Dark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe. Dark matter is called "dark" because it does not appear to interact with the electromagnetic field, which means it does not a .... History The project is a grouping effort, involving many researchers in the Spanish community with a special interest in dark matter. It began on 17 December 2009 and is funded for five years. The project is supported by Consolider-Ingenio, a programme of the Ministry of Economy and Finance. Goals *To analyse in detail the most plausible candidates for dark matter. *To investigate how they form the dark halos that are believed to surround galaxies. *To contribute to the development of experiments to detect dark matter.

Dark Matter
Dark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe. Dark matter is called "dark" because it does not appear to interact with the electromagnetic field, which means it does not absorb, reflect, or emit electromagnetic radiation and is, therefore, difficult to detect. Various astrophysical observationsincluding gravitational effects which cannot be explained by currently accepted theories of gravity unless more matter is present than can be seenimply dark matter's presence. For this reason, most experts think that dark matter is abundant in the universe and has had a strong influence on its structure and evolution. The primary evidence for dark matter comes from calculations showing that many galaxies would behave quite differently if they did not contain a large amount of unseen matter. Some galaxies would not have formed at all and others would not move as they currently do. Other lines of evidence include observa ...

Ministry Of Economy And Finance (Spain)
The Ministry of Economy and Finance (MEH) was a ministerial department in the Government of Spain that merged the traditional ministries of Finance and Economy, with competences on economic affairs, public finance and budgets. It was established on two occasions: the first time during the premierships of Felipe González (1982–1996) and the first term of José María Aznar (1996–2000), and the second time during the premiership of José Luis Rodríguez Zapatero José Luis Rodríguez Zapatero (; born 4 August 1960) is a Spanish politician and member of the Spanish Socialist Workers' Party (PSOE). He was the Prime Minister of Spain being elected for two terms, in the 2004 and 2008 general elections. ... (2004–2011). Due to its size and the vast amount of competences on economic and finance affairs under its control, it has been often dubbed as a "superministry".

Dark Halo
According to modern models of physical cosmology, a dark matter halo is a basic unit of cosmological structure. It is a hypothetical region that has decoupled from cosmic expansion and contains gravitationally bound matter. A single dark matter halo may contain multiple virialized clumps of dark matter bound together by gravity, known as subhalos. Modern cosmological models, such as ΛCDM, propose that dark matter halos and subhalos may contain galaxies. The dark matter halo of a galaxy envelops the galactic disc and extends well beyond the edge of the visible galaxy. Thought to consist of dark matter, halos have not been observed directly. Their existence is inferred through observations of their effects on the motions of stars and gas in galaxies and gravitational lensing. Dark matter halos play a key role in current models of galaxy formation and evolution. Theories that attempt to explain the nature of dark matter halos with varying degrees of success include cold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galaxies
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek ' (), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a hundred million stars, to the largest galaxies known – supergiants with one hundred trillion stars, each orbiting its galaxy's center of mass. Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies. Galaxies are categorized according to their visual morphology as elliptical, spiral, or irregular. Many are thought to have supermassive black holes at their centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. As of ...
