Why does the dark matter is located on the interior of the galaxies?

Dark matter accumulates mainly in the inner part of the Galaxy, but partly outside of the Galaxy there is a halo of gas composed primarily of ions, according to this study the dark matter would be over this gas, but in another State of matter, this gas at lower speed of rotation of the Galaxy would you change phase, by which this gas would be on the inside of the galaxies, in the form of ion crystals.

Introduction;

Much of the universe is made of a component that does not interact with light, but that is matter, because it generates gravitation, so is called dark matter, and is five times more abundant than the matter that we know and we can observe. A research published today in Nature Physics demonstrates for the first time the presence of dark matter in the internal regions of the Milky Way. An international group of scientists has examined the measures of the rotation of the galaxy existing and has been found that can be explained only if there are large quantities of dark matter between the earth and the center of this set of stars, what is known as the interior of our galaxy.

New data from collisions of protons of high-speed in Large Hadron Collider in Europe (LHC) showed a particle exotic nicknamed the "quark beauty" is behaving as predicted by the Standard Model. Previous attempts to measure the processing rare beauty of quark in one of the so-called contradictory results "quark up" had ceded. This led scientists to propose an explanation beyond the standard model.

Supersymmetry, SUSY, for short, is one of the alternatives proposed to explain these inconsistencies, postulating the existence of a heavier "brother" of every particle in the universe.

Supersymmetry, developed to fill the gaps in our understanding of particles and forces known, postulates that every fundamental particle has a supercompanero still-to-be-discovered. It turns out that the lightest of the Group has properties that make it one of the main of the dark matter.

"The lightest supersymmetric WIMP is stable and is not allowed to decay into other particles.

Where are the missing baryons? Perhaps in a diffuse gaseous halo around the Milky Way. X-ray satellites have detected oxygen atoms in our galaxy that have lost most of their eight electrons, a sign they inhabit gas that is millions of degrees hot—far hotter than the surface of the sun. But since we don’t know how far these fried oxygen atoms are from us, we can’t accurately gauge the size of this component of the galaxy. If they're fairly close to the disk, then this so-called circumgalactic medium isn't extensive and therefore doesn't amount to much. But if they're far away, spread throughout a gargantuan halo, this gaseous material could outweigh all of the galaxy's stars, providing fuel for star formation for billions of years to come.

A ion or ion1 ( "going", in Greek; ἰών [ion] is a charged particle electrically formed by an atom or molecule that is electrically neutral. Conceptually this can be understood as, from a neutral state of an atom or particle, have gained or lost electrons; this phenomenon is known as ionization.

A Crystal or crystalline solid is a solid material of whose constituents, such as atoms, molecules, or ions are arranged in a microscopic highly ordered structure, forming a crystalline network extending in all directions.

The crystals are distinguished by the anisotropy of properties (it is not the same in all directions) and by the existence of elements of symmetry.

As the Crystal is electrically neutral, if the ions have different load this will determine the stoichiometry and, therefore, structure and the index of coordination.

Ionic crystals have two important characteristics: they consist of loaded links and anions and cations are usually of different sizes. It is hard and brittle at the same time. The force that holds them is electrostatic and with a high melting point.

Results;

The dark matter accumulates mainly in the inner part of the galaxies, and in the part of outside of the galaxy there is a halo of gas consisting mainly of ions, also the best candidate of dark matter known as WIMP, in addition to not having been detected by the scientific laboratories of the world, scientists found the answer to the anomaly within the standard model, which would leave it virtually unsupported theoretical.

Based on this information I can conclude that the dark matter, with characteristics that scientists know it (invisibility, effect lens and anisotropy), lies mainly in the center of galaxies, because the rotation speed is slower than on the inside that on the outside of the celestial bodies and galaxies, on the assumption that the dark matter is made up of crystals Ionic , which for its high melting point, the be exposed to greater speed of rotation, this with would lead to a change of phase, a neutral Ionic Crystal in the inner Galaxy, to an ionic gas in the outer part of the Galaxy, which leads to another conclusion that the halo of ionic gas that surrounds the Galaxy is also dark matter.

We can also say that these ionic crystals, with its features of electrostatic and high melting point, can generate an electric field the be in contact with each other, or the enter in contacts with other solid materials, and their characteristic of high fusion makes it sensitive to phase changes quickly. Now based on the principle that the dark matter fills the universe, and their behavior in the galaxy should be equal on earth, we can say that the force electrostatic on earth, mainly the one that we experience in cold climates, is produced mainly by these ionic crystals in the air.

Conclusion;

Dark matter, with characteristics that scientists know it (invisibility, effect lens and anisotropy), lies mainly in the center of galaxies and celestial bodies, because the speed of rotation in the interior part of the celestial bodies and galaxies is slower.
