Singlet scalar dark matter in noncommutative space
In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered, but our information about the nature of dark matter is still limited. There are such particle candidates as scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...
متن کاملSearching for Dark Matter
The observational evidence for dark matter on progressively larger cosmic scales is reviewed in a rather pedagogical fashion. Although the emphasis is on dark matter in galaxies and in clusters of galaxies, its cosmological evidence as well as its physical nature are also discussed.
متن کاملStructure Formation with Generalized Dark Matter
The next generation of cosmic microwave background (CMB) experiments, galaxy surveys, and highredshift observations can potentially determine the nature of the dark matter observationally. With this in mind, we introduce a phenomenological model for a generalized dark matter (GDM) component and discuss its e†ect on large-scale structure and CMB anisotropies. Specifying the gravitational inÑuenc...

A review of the development of the concept of dark matter is given. The dark matter story passed through several stages on its way from a minor observational puzzle to a major challenge for theory of elementary particles. I begin the review with the description of the discovery of the mass paradox in our Galaxy and in clusters of galaxies. First hints of the problem appeared already in 1930s an...
متن کاملDark Matter: Motivation, Candidates and Searches
The physical nature of most of the gravitating mass in the universe is completely mysterious. The astrophysical evidence for the presence of this dark matter and astrophysical constraints on its properties will be reviewed. The most popular dark-matter candidates will be introduced, and current and future attempts to search for them directly and indirectly will be discussed.
