Dark matter and dark radiation
Lotty Ackerman, Matthew R. Buckley, Sean M. Carroll, and Marc Kamionkowski California Institute of Technology, Pasadena, California 91125, USA (Received 16 December 2008; published 23 January 2009) We explore the feasibility and astrophysical consequences of a new long-range Uð1Þ gauge field (‘‘dark electromagnetism’’) that couples only to dark matter, not to the standard model. The dark matter...
متن کاملSinglet 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 کاملDark Matter and Dark Energy
I briefly review our current understanding of dark matter and dark energy. The first part of this paper focusses on issues pertaining to dark matter including observational evidence for its existence, current constraints and the ‘abundance of substructure’ and ‘cuspy core’ issues which arise in CDM. I also briefly describe MOND. The second part of this review focusses on dark energy. In this pa...
متن کاملFrom Dark Energy & Dark Matter to Dark Metric
It is nowadays clear that General Relativity cannot be the definitive theory of Gravitation due to several shortcomings that come out both from theoretical and experimental viewpoints. At large scales (astrophysical and cosmological) the attempts to match it with the latest observational data lead to invoke Dark Energy and Dark Matter as the bulk components of the cosmic fluid. Since no final e...
متن کاملThe dark side of cosmology: dark matter and dark energy.
A simple model with only six parameters (the age of the universe, the density of atoms, the density of matter, the amplitude of the initial fluctuations, the scale dependence of this amplitude, and the epoch of first star formation) fits all of our cosmological data . Although simple, this standard model is strange. The model implies that most of the matter in our Galaxy is in the form of "dark...
