Dark matterThe phenomenological implications of the eleven dimensional limit of $M$-theory (strongly coupled $E_8\times E_8$) are investigated. In particular we calculate the supersymmetric particle spectrum subject to constraints of correct electroweak symmetry breaking and the requirement that the ...
Hot Dark Matter In subject area: Physics and Astronomy Hot dark matter refers to a type of dark matter composed of massive and high-velocity components, such as neutrinos, which have relativistic speeds. This type of dark matter tends to spread structures like galaxies and is believed to consti...
The main target this paper is to check a theory about dark matter nature, which was published by the author in previous papers. It was postulated it that dark matter density is a function which depend on E, gravitational field. In this work has been calculated a new function for DM densit...
We know a lot about dark matter (DM). First of all we know it exists: modified gravity models cannot explain the spatial segregation between the regions where most of the mass is and where most of the visible matter is in the "bullet cluster" (1) (a cluster formed by two colliding ga...
Effective field theory of modified gravity with two scalar fields: dark energy and dark matter We present a framework for discussing the cosmology of dark energy and dark matter based on two scalar degrees of freedom. An effective field theory of cos... LÁ Gergely,S Tsujikawa - 《Phys.rev...

Instead, the primary theory of dark matter says that it is made of hypothetical particles called Weakly Interacting Massive Particles (WIMPs), which are about as well understood as their catch-all name implies. WIMPs don't even seem to interact with each other through anything more than gravity...

If this LCDM theory is correct, then we know, within a certain range of uncertainty, which dark matter halo the Milky Way (MW) has, which dark matter halo the Large Magellanic Cloud (LMC) has, and which dark matter halo the Small Magellanic Cloud (SMC) has. The uncertainties on the da...
